Feature
●【4-in-1 Water Quality Meter】The tester has the functions of monitoring TDS, pH, EC meter and temperature measurement. With this convenient PH tester, you can complete your work faster and easier than ever!
●【Easy to Use Digital PH Meter】Just remove the pH pen protective cap and immerse the ph water tester electrode in the solution and press the button to be measured. Dont worry about seeing the displayed value when there is insufficient light.Tester features Backlit LCD to help you see the measurement clearly in any situation.
●【High Accuracy】: With high sensitive glass probe, you can get a full measurement range of 0-14pH, 0.01 pH resolution. Green Backlit LCD Design guarantees that you can read the measuring results in any condition.
●【Automatic Temperature Compensation】: Auto temp compensation (ATC) ensures accuracy in various temperatures (32°F~140°F), It can solve the possible error perfectly caused by the change of liquid temperature, so as to make the pH readings more accurate.
●【Multi-purpose Test】Portable Water Quality Meter can be carried anywhere to measure water quality such as Hydroponics, Drinking Water, tap water, RO system water, aquarium, seawater, pool water, etc.

How to Calibrate the pH Meter?
Take ph 6.86 standard solution calibration as an example:
1. Press the ON/OFF button to turn on the meter, and then press MODE/CAL button adjust the tester to pH mode;
2. Put the electrode into pH 6.86 standard solution, waiting for the readings to stabilize (usually 5~10 Seconds);
3. Press and hold the MODE/CAL button and release after 6 seconds;
4. Until the readings of pH 6.86 is no longer flashing, the calibration of pH 6.86 is completed;
5. Repeat the above steps if you need to calibrate pH 4.00 or pH 9.18.
How to make a standard solution to calibrate:
1. Completely empty the powder into a clean 250ml glass beaker;
2. Add 250ml of PH Buffer Powder to the beaker;
3. Still until the powder has completely dissolved;
4. pH solution accuracy is ±0.01pH;
5. The prepared solution can be sealed with plastic film and placed Fresh Keeping in the refrigerator for next calibration within one month.
