WideRange TDS-3 Pro – 0 to 99990 ppm Digital TDS & Temperature Meter | Pocket Clip | Auto Off | HOLD | CE Certified

WideRange TDS-3 Pro — The TDS Meter That Handles Pakistan's Most Extreme Water

Most TDS meters in Pakistan measure up to 9990 ppm. For households with municipal water or standard bore water, that range is enough. But Pakistan's water reality is far more varied than that. In coastal areas of Karachi, seawater-affected bore water can exceed 15,000 ppm. In agricultural zones of Sindh and southern Punjab, saline groundwater regularly reads above 20,000 ppm. Industrial discharge zones, water tanker supplies, and unchecked bore water sources can push TDS levels well beyond what a standard 9990 ppm meter can even display.

The WideRange TDS-3 Pro measures up to 99990 ppm — covering every water source in Pakistan from the purest RO output (under 10 ppm) to the most heavily contaminated or saline water sources (up to 99990 ppm). It is the widest-range TDS meter available in Pakistan under Rs. 1,500 and the only one that gives home users, RO technicians, and field workers a single device that handles every water testing scenario they will ever encounter.

0 to 99990 ppm — 10× the range of standard TDS meters. One device covers pure RO water, hard bore water, saline sources, agricultural water, and industrial samples. No other TDS meter under Rs. 1,500 in Pakistan measures this range.

Understanding the Dual-Range Display — What Does ×10 Mean?

The WideRange TDS-3 Pro uses a dual-range display system that some buyers find confusing the first time they use it. Here is exactly how it works:

In simple terms: when the ×10 symbol appears on the display, multiply what you see by 10 to get the actual ppm reading. This is a standard feature of wide-range TDS meters that allows a compact display to show readings across a 99990 ppm span. Once you understand it, it takes zero extra effort — the display shows the value, and if the ×10 symbol is present, you multiply.

Important: If the ×10 symbol is on your display, do NOT read the number as shown. Multiply by 10 for the accurate reading. Example: display shows 650 with ×10 = your actual TDS is 6500 ppm.

H2: Who Uses the WideRange TDS-3 Pro in Pakistan?

This meter serves two buyer types from a single device:

For Home and Family Use:

• Families Checking Drinking Water — Test your tap water, RO filtered water, or bottled water daily. Know instantly if your TDS is in the safe zone (under 500 ppm for drinking water) without needing any technical knowledge.
• RO Plant Owners — Check both input and output TDS of your home RO system. If input is 800 ppm and output is above 50 ppm, your membrane needs servicing. The WideRange TDS-3 Pro handles both readings without any range limitation.
• Aquarium Hobbyists — Monitor freshwater mineral balance and marine tank salinity. Marine aquarium water typically reads 30,000–35,000 ppm — which standard 9990 ppm meters cannot measure. The WideRange TDS-3 Pro handles this comfortably.
• Agriculture and Gardening — Test irrigation water and hydroponics nutrient solutions. Agricultural canal water in Pakistan can read 2000–8000 ppm in saline zones — the WideRange TDS-3 Pro gives you accurate readings across this entire agricultural range.

For RO Technicians and Field Workers:

• RO Plant Installation and Service — Field technicians need a meter that covers every water type they encounter on different jobs. One day testing a 250 ppm municipal supply in Islamabad, the next testing 2500 ppm bore water in Multan — the WideRange TDS-3 Pro handles both without changing meters.
• • Pocket Clip for Field Carry — The built-in pocket clip on the back of the meter (visible in product images) clips directly onto a uniform pocket, shirt pocket, or tool vest. Technicians carry it hands-free between tests without putting it down. No other TDS meter in this price range at Axtron offers this practical field feature.
  • Water Tanker and Source Testing — Field workers testing water tanker quality, bore water for new construction sites, or canal water for irrigation projects need 99990 ppm range. Standard meters are useless here.
  • Multiple Site Testing — The HOLD function locks readings while you record them in your service sheet without rushing. The 5-minute auto-off means you never drain the battery by forgetting to switch off between sites.

   

  Key Features of the WideRange TDS-3 Pro

  • 0–99990 ppm Ultra-Wide Range — Measures ten times wider than standard 9990 ppm TDS meters. Covers pure RO water, hard bore water, saline water, agricultural irrigation water, marine aquariums, and industrial water sources.
  • Dual Resolution Display — 1 ppm resolution for readings 0–999 ppm (accurate for pure water monitoring). 10 ppm resolution with ×10 display multiplier for readings 1000–99990 ppm (wide range field measurements).
  • Temperature Measurement — Built-in thermometer shows water temperature alongside TDS reading. Water temperature affects TDS readings — checking both simultaneously gives more accurate field data.
  • HOLD Function — Freezes the current reading on the LCD display for easy recording. Essential for field technicians logging multiple readings across different water points on a single visit.
  • 5-Minute Auto Off — Automatically powers down after 5 minutes of non-use. Protects battery life during busy field days when you cannot always remember to switch off between tests.
  • Built-In Pocket Clip — Moulded pocket clip on the back of the meter body. Clips to shirt pocket, uniform breast pocket, or tool vest for hands-free carry between test points. Exclusive feature for field technicians.

  • Protective Probe Cap — Included cap protects the electrode tip when not in use. Always replace cap after testing and rinse probe with clean water.
  • 2 × 1.5V Button Cell Batteries — Standard button cells included. Widely available at any mobile phone shop, stationery store, or electronics market in Pakistan.

   

  Safe Use Instructions

  These safety instructions are important to share with buyers. Incorrect use is the leading cause of TDS meter inaccuracy and damage in Pakistan.

  DO NOT submerge the entire meter body in water. Only the probe tip section (below the probe cap line) should enter the water. Submersion beyond the maximum immersion level will damage the internal electronics permanently.

  Storage: Do not store the meter in high-temperature environments or in direct sunlight. Heat damages the LCD display and battery. Keep in a cool, dry location — a drawer, tool kit, or carry pouch.

  Handling: Avoid dropping, striking, or applying heavy pressure to the meter body. The LCD and electrode connections are precision components that can be damaged by physical impact.

  After Testing: Always rinse the probe tip with clean distilled water or RO water after each test. Residual minerals on the probe affect future reading accuracy.

  Filter Check: Use the WideRange TDS-3 Pro to regularly check the output TDS of your water filter or RO plant. Rising output TDS over time indicates it is time to replace your filter cartridge or RO membrane.

   

  How to Use the WideRange TDS-3 Pro

  Step 1: Remove the protective cap from the probe tip. Press the ON/OFF button to power on the device.

  Step 2: Dip only the probe tip into your water sample — up to the maximum immersion line marked on the probe section. Do not submerge the meter body.

  Step 3: Wait 10–15 seconds for the reading to stabilise on the LCD display.

  Step 4: Check whether the ×10 symbol is displayed. If not, read the number directly. If ×10 is shown, multiply the displayed number by 10 for the actual TDS in ppm.

  Step 5: Press TEMP to switch to temperature mode and read the water temperature in °C or °F.

  Step 6: Press HOLD to freeze the reading for recording. Press ON/OFF to power off, or leave it — auto-off activates after 5 minutes.

  Step 7: Rinse the probe tip with clean water after every test. Replace the protective cap. Clip to pocket or store in case.

  H2: Frequently Asked Questions

  Q: What does the ×10 symbol mean on the display?

  A: When the ×10 symbol appears on the LCD, it means the actual TDS reading is 10 times higher than the number shown on the display. This is how the meter displays readings above 999 ppm on a compact screen that spans a 99990 ppm range. Example: if the display shows 475 with the ×10 symbol, your actual TDS is 4,750 ppm. If the display shows 475 without the ×10 symbol, your TDS is 475 ppm. Once you understand this, it is completely straightforward — the ×10 symbol is simply your cue to multiply by 10.

  Q: How is this different from the AquaCheck Pro also sold by Axtron?
  

  A: The key difference is measurement range and design purpose. The AquaCheck Pro (Rs. 1,800) measures 0–9990 ppm with a titanium probe for long-term accuracy and durability — ideal for regular home and RO plant monitoring where precision over time matters. The WideRange TDS-3 Pro (Rs. 1,299) measures 0–99990 ppm — 10 times wider — making it the right choice when you need to test water sources that exceed 9990 ppm, or when you want a field-carry meter with a pocket clip for technician use. If you test only standard drinking water and RO output, either works. If you encounter high-mineral bore water, saline sources, agricultural water, or marine aquariums, only the WideRange TDS-3 Pro covers the full range.

  Q: My water reads above 9990 ppm. Can this meter measure it accurately?

  A: Yes — this is exactly what the WideRange TDS-3 Pro is designed for. It measures up to 99990 ppm with ±2% accuracy across the full range. When your reading is above 999 ppm, the ×10 display mode activates automatically. Multiply the displayed number by 10 and you have your accurate TDS reading. For Pakistan's most extreme water sources — deep bore water in Sindh, saline agricultural water, seawater-affected coastal supplies — the WideRange TDS-3 Pro is the correct meter to use.

  Q: Can I use this as my daily home TDS meter if my water is below 500 ppm?

  A: Absolutely. The wide range does not reduce accuracy at lower readings — the meter gives 1 ppm resolution for readings below 999 ppm, which is exactly what you need for checking RO output water (typically 10–50 ppm) and drinking water quality (typically 100–500 ppm). The wide range is simply an added capability that most home users will rarely need but technicians and field workers rely on daily.

  Q: I am an RO technician. Why is the pocket clip useful?

  A: When you are servicing an RO plant, your hands are occupied with tools, fittings, and tubing. Putting a TDS meter down on a wet surface risks damage and losing your reading. The WideRange TDS-3 Pro's built-in pocket clip means you clip it to your shirt or vest pocket and it stays with you hands-free while you work. You pick it up, dip, read, HOLD the reading, replace it in your pocket, and continue working — all without setting it down. For technicians doing 5–10 service visits a day, this saves significant time and keeps the meter safe.

  Q: How do I check if my RO filter needs replacement using this meter?

  A: Test your raw feed water (tap or bore) and record the TDS. Then test your RO output water. A healthy RO membrane removes 90–99% of TDS. If your feed water is 600 ppm, your output should be 6–60 ppm. If your output TDS is rising above 10% of your input reading, your membrane or post-filters need checking. For example, if your feed is 600 ppm and output is now 120 ppm (20% of input), your membrane rejection rate has dropped and servicing is due. Use the WideRange TDS-3 Pro for monthly monitoring to catch this early.
