Simplify Your Water Analysis

Inconsistent water quality can ruin a harvest or halt a production line. To stay in control, you need a tool that delivers speed and accuracy. The pH/Temperature Tester with 0.1 pH resolution offers the perfect balance of professional performance and everyday ease. It eliminates the guesswork of paper strips and bulky lab equipment.

Dual Measurement Power

Temperature heavily influences pH readings. This digital tester solves that problem by measuring both variables simultaneously. It uses Automatic Temperature Compensation (ATC) to adjust your results in real-time. This ensures your data stays valid even when the liquid temperature fluctuates.

• Sharp Resolution: The 0.1 pH increment provides the clarity you need for pools, tanks, and hydroponic systems.

• Integrated Thermometer: Stop carrying two tools. View both readings on a large, easy-to-read LCD.

• Rugged Design: Most models feature a waterproof housing. You don't have to worry about accidental drops in the tank.

• Long Battery Life: Efficient circuitry allows for hundreds of tests before a battery swap is necessary.

How to Maximize Performance

Operating the device is easy. Simply dip the sensor into your sample and stir gently. Wait for the stability icon to appear on the screen. For the best results, calibrate your tool regularly using a standard buffer solution. Always rinse the probe with distilled water after every use to prevent salt buildup.

Reliable Accuracy for Everyone

Brewers, growers, and lab techs all trust this tester for its durability. It fits comfortably in your pocket but provides industrial-grade feedback. Whether you are checking a swimming pool or a nutrient reservoir, this device delivers confidence.
