YIERYI TDS/pH/TEMP 3 in 1 Water Quality Test Pen Temperature Automatic Temperature Test Pen pH

3 IN 1 WATER QUALITY TEST: PH meter is designed with 3-in-1 function, which can be measured PH, TDS, and temperature simultaneously with high precision. omnidirectional measurement of water quality to ensure the health of water quality.

HIGH ACCURACY: TDS meter for checking TDS/salt (NaCl) levels freshwater aquariums, ponds, and water purification systems. this tester has a sensitive electrode sensor to read accurate PH levels. the included detailed manual will show you how to get the best accurate and stable reading. 

AUTO CALIBRATION: The TDS/PH meter has an auto temperature compensation feature that adjusts to water temperatures and water quality to give PH readings almost instantly. as well, you can calibrate the tester with a one-touch button using buffer powder.

AUTOMATIC TEMPERATURE COMPENSATION: No more need to take care about the temperature of testing liquid, as PH meter has built-in (ATC) automatic temperature compensation, so that it can accurately determine pH value of the sample at any temperature in a range of 0°C - 60°C (32°F - 140°F).

WIDE USE: Pocket size TDS PH meter is the ideal test kit for home and laboratory uses. Ideal use to test for water, pools, aquariums, spas, hydroponics, food, wine and beer making, and more.
