Feature
●4-in-1 pH Meter: GISNPA pH tester can simultaneously measure pH, ORP, H2, and temperature, with a large and wide measurement range, providing comprehensive water quality information. Very suitable for measuring drinking water, swimming pools, ponds, beer brewing, kombucha, aquariums, hydroponics, laboratories, and food processing.
●3-Point Calibration: The pH meter features a high-sensitivity glass probe, offering a complete measurement range from 0 to 14 pH with a remarkable 0.01 pH resolution. To ensure measurement accuracy, our pH meter employs a meticulous three-point calibration process, which involves precise adjustments using pH solutions at 4.00, 6.86, and 9.18. Our ORP and H2 meters come pre-calibrated for your convenience.
●PH Meter with Automatic Temperature Compensation: Temperature can influence reading accuracy, but our digital pH meter features automatic temperature compensation to ensure the most precise readings. Unlike some other pH meters for water with a limited range of 0°C-50°C, our pH meter excels with a broader range of 0°C-60°C (32°F-140°F). This expanded range effectively mitigates potential errors resulting from fluctuating liquid temperatures, enhancing the accuracy of pH readings.
●Automatic Power-Off Function and Backlit Display: Our pH meter includes an automatic power-off feature, which conserves power by turning it off after 5 minutes of inactivity. Additionally, the pH meter is equipped with a green backlit LCD, ensuring that measurement results are clearly visible in all conditions.
●Reading Lock Function: Press the "HOLD/TEMP" key to easily lock the readings, making it easy for you to accurately record your measurements, and press again to unlock it.
Description
How to Calibrate the pH Meter?
1. Before calibration, prepare 3 beakers containing separately 250ml of pH 4.00/pH 6.86/pH 9.18 standard solution.
2. Rinse the electrode with clean distilled water and wipe it dry. Turn on the pH meter and adjust to pH mode.
3. Immerse the electrode into the pH6.86 buffer solution, wait for the value to stabilize, press "CAL" for 5s, and the screen will display "CAL", when pH6.86 flashes 3 times, the calibration of pH6.86 is finished.
4. Repeat the above steps to calibrate pH4.00 or pH9.18.
