pH Meter, Digital PH Tester Pen 3 pH Calibration Powders ±0.01 pH Accuracy Pocket Size, LCD Display for Household Drinking, Pool and Aquarium

【3-in-1 pH Meter】 pH meter has a three-in-one function, which can measure PH, TDS and temperature with high precision at the same time. All-round measurement of water quality to ensure healthy water quality.
【Automatic Calibration pH Tester】With high sensitive glass probe, you can get a full measurement range of 0-14pH. This pH meter uses a 3-point calibration method to calibrate the electrode to solutions with pH 4.01, pH 6.86, and pH 9.18 pH powder. You can calibrate effortlessly to ensure the accuracy of your measurements.
【High Accuracy pH Meter for Water】0.01 Resolution High-accuracy algorithm chip and electrode of our TDS meter digital pH meter ensure accurate and fast response. Green Backlit LCD Design guarantees that you can read the measuring results in any condition. One-button lock reading function helps lock reading even if the tds Meter is taken out of the sample!
【Automatic Temperature Compensation Digital pH Meter】No longer need to pay attention to the temperature of testing liquid, pH meter can accurately determine the pH value of the sample in the temperature range of 32°F-140°F(0°C-60°C), so as to solve the inaccurate problem caused by changing the liquid temperature.
【pH Meter to Improve Water Quality】This pH/TDS meter can help you find out quality water value. Water with equal pH, TDS levels are perfect for people’s daily needs for drinking water. For plants and aquaculture animals, they can grow more fast and health if they drink good quality pH, TDS value of the water test by this pH meter.
【Pocket Size pH Meter for Water】 You can use this small pocket size but powerful pH meter device to measure your aquarium, pool, pond in a garden, bath tub to test the levels of pH value. The digital ph meter can also be used to measure drinking water, RO System, spa, soap mixtures, wine, beer or any other liquids.
【How to calibrate the pH Meter/TDS Meter?】 1. Add pH4.01/pH6.86/pH9.18 buffer powder into water and stir it. 2. Press the ON/OFF button and adjust to pH mode. Put the electrode into pH4.00/pH6.86/pH9.18 standard solution and wait 5~10 seconds. 3. Press and hold the MODE/CAL button and release after 6 seconds; wait pH4.00/pH6.86/pH9.18 flash 3 times till readings are no longer flashing, finish the pH calibration.
【Tips】 For better using experience, we recommend to soak the tds meter digital water tester in clear water for 5 minutes before starting calibration after receive the product. Because it may cause inaccurate readings if customer immediate use for the first time.
