4-in-1 Water Quality Test: 4-in-1 pH tester, which can measure PH, ORP (Oxidation-reduction potential), H2 (Hydrogen content), and Temp value with high precision at the same time, simply press the {MODE/CAL} key to switch the readings of pH, ORP (mV), and H2 (ppb/ppm).
±0.05 pH Accuracy and 3-Point Calibration: It has a high-sensitivity glass probe, the full measurement range of the pH meter is 0-14ph, and the pH resolution is 0.01. And the pH meter uses the three-point calibration method to calibrate the electrode to the solution of pH 4.00, pH 6.86, and pH 9.18 to ensure the accuracy of measurement. ORP and H2 meters are pre-calibrated.
pH Meter with Automatic Temperature Compensation: Temperature will affect the reading level, and automatic temperature compensation can ensure that you get the best reading. compared with other pH meters for water, there is only a range of 0°C-50°C. our digital pH meter has a better range of 0°C-60°C (32°F-140°F). therefore, it can solve the possible errors caused by the perfect change of liquid temperature, so as to make the pH reading more accurate.
Automatic Power-Off Function & Backlit Display: The automatic power-off function turns off the power after 5 minutes without any operation to save power. The pH meter features a green backlit LCD to help you obtain the measurement results clearly in any situation. Press the "HOLD/TEMP" key to lock the reading, helping to easily record the reading.
pH Tester with Wide Application: Ideal for household and laboratory pH testing applications, including drinking water, swimming pool, water treatment, pond, water purification, aquariums, hydroponics, laboratory, etc.
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.

9. Reset function: Turn it on,Press the ON/OFF key for 3 seconds , and then release it. When "----" appears on the screen, the reset is successful.
How To Use :
1. Remove protective cap.
2. First rinse the electrode with distilled water and suck it with filter paper.
3. Turn the meter on by pressing "ON/OFF" key.
4. Immerse the pH meter electrode in the solution to be tested (should not be over the immersion line).
5. Stir gently and wait around 30 seconds till the reading stabilizes.
6. After finishing, clear the electrode with pure water, turn the meter off by pressing "ON/OFF" key.
7. Always replace the protective cap after use.
Kindly Reminder:
1. If the tester was used or lay aside long time: recalibrate it.
2. If you open battery case or replace battery: recalibrate it.
3. The glass bulb of the electrode is fragile. Don't touch it by hard tools and fingers, suck the water on it gently when cleaning.
Reset function: Turn it on,Press the ON/OFF key for 3 seconds , and then release it. When "----" appears on the screen, the reset is successful.
