AquaCheck Pro – 2-in-1 Digital TDS & Temperature Water Purity Meter — Pakistan's Most Reliable Everyday Water Purity Checker
Clean drinking water is not a luxury — it is a basic necessity. Yet millions of households across Karachi, Lahore, Multan, Islamabad, Faisalabad, and Rawalpindi use tap water, bottled water, or RO filtered water without ever verifying its actual purity. The AquaCheck Pro 2-in-1 Digital TDS and Temperature Meter changes that. In under five seconds, it gives you an accurate reading of your water's Total Dissolved Solids (TDS) in ppm and its current temperature in both Celsius and Fahrenheit — so you always know exactly what you and your family are drinking.
What Is TDS and Why Should You Check It?
TDS stands for Total Dissolved Solids — the total concentration of all dissolved substances in water, including minerals, salts, metals, and chemicals. It is measured in ppm (parts per million) or mg/L. Here is what the numbers mean for you:
| TDS Level (ppm) | Water Quality | Recommended Action |
| 0 – 50 ppm | Excellent — Pure RO output water | Safe to drink directly |
| 50 – 150 ppm | Good — Ideal for drinking water | Acceptable for all uses |
| 150 – 300 ppm | Acceptable | Suitable for drinking, monitor regularly |
| 300 – 500 ppm | Fair — WHO acceptable limit | Consider a water filter |
| 500 – 1000 ppm | Poor quality | RO filter or water treatment recommended |
| Above 1000 ppm | Unsafe for drinking | Do not use for drinking or cooking |
In cities like Multan and Bahawalpur, groundwater TDS often exceeds 800–1200 ppm. In Karachi's older neighbourhoods, pipe contamination regularly pushes TDS above 600 ppm. With the AquaCheck Pro, you can check your water in seconds — any time, anywhere.
Key Features of the AquaCheck Pro Water Purity Meter
- Titanium Probe Electrode — Unlike cheap stainless steel probes that oxidise over time and give drifting readings, the AquaCheck Pro uses a titanium alloy probe that resists corrosion and maintains accuracy across thousands of tests.
- 2-in-1 Measurement — Measures both TDS (water purity in ppm) and Temperature (°C/°F) from a single device. No need to carry separate thermometers or basic-only TDS pens.
- Wide Range 0–9990 ppm — Covers everything from ultra-pure RO output water (under 10 ppm) to heavily contaminated groundwater above 1000 ppm. One meter works for all water types.
- Factory Calibrated, Ready to Use — No calibration setup needed. Remove from the protective case, switch on, and test immediately.
- Auto Shut-Off After 5 Minutes — Saves battery life automatically when you forget to turn it off. Battery (CR2032, widely available in all Pakistan markets) lasts for hundreds of tests.
- Clear LCD Display — Digital readout is easy to read indoors and outdoors. Dual-line display shows TDS and temperature together.
- Protective Storage Case Included — Comes in a hard transparent carry case that protects the probe tip and keeps the meter safe in your field kit, lab drawer, or kitchen shelf.
- Pocket-Size Portability — Slim pen design fits in any pocket, lab coat, or tool bag. Take it to your RO plant site, factory floor, school lab, or simply keep it in your kitchen drawer.
What Can You Test with the AquaCheck Pro?
- Tap Water — Check municipal water quality before drinking or cooking. Know exactly what is coming through your pipes.
- RO Filtered Water — Verify your RO system is performing correctly. If your RO output TDS is above 50 ppm, your membrane or post-filter needs attention.
- Bottled Water — Compare different bottled water brands. You may be surprised at what you are actually paying for.
- Aquarium Water — Maintain the correct mineral balance for freshwater fish. Sudden TDS spikes signal water quality issues before fish show symptoms.
- Spring and Well Water — Test natural water sources before using for drinking, cooking, or irrigation.
- Any Other Water Source — Rainwater collection, water tankers, hospital supply lines, school water coolers — test anything, anywhere, in seconds.How to Use the AquaCheck Pro — Simple 4-Step Process
Step 1: Remove the protective cap from the probe tip at the bottom of the meter.
Step 2: Press the ON/OFF button. The LCD display will light up and show the current reading.
Step 3: Dip the probe tip into your water sample, at least 2–3 cm deep. Hold still for 3–5 seconds until the reading stabilises.
Step 4: Press TEMP to switch between TDS and Temperature mode. Press HOLD to lock the reading for recording. Press ON/OFF to turn off, or let the auto shut-off handle it after 5 minutes.
After each test, rinse the probe with distilled water or clean RO water and replace the protective cap. This keeps your readings accurate long-term.

Q: What is the difference between the AquaCheck Pro and the 5-in-1 MF-M51 water meter also sold by Axtron?
A: The AquaCheck Pro is a focused 2-in-1 device for TDS and Temperature — ideal for everyday home and RO plant use at an affordable price of Rs. 1,800. The MF-M51 5-in-1 meter also measures EC, pH, and Salinity, making it better suited for labs, factories, and industrial applications. If you just want to check your drinking water or RO output daily, the AquaCheck Pro is the right choice. If you need full water chemistry analysis, go with the MF-M51.
Q: How do I know if my RO filter is working correctly using this meter?
A: Test your tap water (input) first and note the TDS reading. Then test the water coming out of your RO tap (output). If your RO system is working correctly, the output TDS should be 90–95% lower than the input. For example, if your tap water is 600 ppm, your RO output should be 30–60 ppm. If the output is above 100 ppm, your RO membrane or post-filters need servicing.
Q: Is the AquaCheck Pro accurate enough for professional use?
A: Yes. The ±2% accuracy is the industry standard for pen-style TDS meters and is sufficient for RO plant monitoring, water quality control, aquarium management, and general industrial use. For high-precision laboratory research requiring ±0.1% accuracy, a benchtop instrument would be needed.
Q: Does it work for testing water in Pakistan's hard water areas like karachi, Lahore, and Rawalpindi?
A: Absolutely. The AquaCheck Pro measures up to 9990 ppm, well above even the highest-TDS groundwater found in Pakistan's hard water zones. It will give you a clear reading regardless of how high the mineral content is.
Q: Where can I buy the AquaCheck Pro in Karachi, Lahore, or other cities?
A: You can order directly from axtronpakistan.com with nationwide Cash on Delivery. We deliver to Karachi, Lahore, Islamabad, Rawalpindi, Multan, Faisalabad, Peshawar, Quetta, Sialkot, Gujranwala, Hyderabad, and all other cities across Pakistan.
Q: How long does the CR2032 battery last?
A: With normal use (a few tests per day) and the auto shut-off feature, a single CR2032 battery lasts for several hundred tests — typically 6 to 12 months of regular home or RO plant use. CR2032 batteries are widely available at any mobile phone shop, electronics store, or supermarket in Pakistan
