Features

1、7 IN 1 WATER QUALITY TESTER: TDS meter adopts a 7 in 1 functional design and can measure PH, ORP, EC, TDS, SALT, S.G, TEMP. Meet all your testing needs and comprehensively test water quality! Comprehensive water quality measurement to ensure healthy water quality.
2、AUTOMATIC CALIBRATION OF PH TESTER: Using a highly sensitive glass probe, it can achieve a full measurement range of 0 to 14 pH and a 0.01 pH resolution. The pH meter uses a three point calibration method to calibrate the electrodes to solutions with pH 4.00, pH 6.86, and pH 9.18. You can easily calibrate to ensure measurement accuracy.
3、EASY TO USE: Simply immerse the electrode in the target solution, and then press and hold the TEMP CAL button after the reading stabilizes (usually 5 to 10 seconds), and the pH meter will automatically calibrate.
4、AUTOMATIC TEMPERATURE COMPENSATION: There is no longer a need to pay attention to the temperature of the testing liquid. The instrument can accurately measure the pH value of the sample within the temperature range of 0 ℃ to 50 ℃, thereby solving the problem of inaccuracy caused by changing the liquid temperature.
5、COMPACT PH METER: Everyone can use this small but powerful pen tester. Easy to carry to different scenes to use.
6、WIDE APPLICATION: Our water tester pen is widely used in hydroponic systems, drinking water, tap water, beer, wine, milk, home brewing, swimming pools, aquariums, hot tubs, aquaculture, spa centers, fish tanks, and urine.
