5 in 1 Water Quality Meter The tester has the functions of monitoring TDS, PH, ORP, EC meter and temperature measurement. With this practical PH tester, you can complete your work faster and easier than ever! Easy to Use Digital PH Meter Simply remove the protective cap of the pH pen and immerse the pH water tester electrode into the solution and press the button to measure. Don't worry about seeing the displayed value when the light is insufficient. The tester has a backlit LCD screen to help you see the measurement clearly in any situation. High Accuracy The high-precision algorithm chip and electrode of our digital water pH tester ensure accurate and fast response. When the measured value is stable, simply press the HOLD/TEMP button to lock the measured value and take it out to view, which is really simple. Automatic Temperature CompensationTemperature can affect reading levels, the digital pH meter for hydroponics has an even better range of 0C to 60C (32F to 140F), automatic temperature compensation can ensure that you get the best reading, so you can test with confidence in any environment. Multi-Purpose TestingThe portable water quality meter can be carried anywhere to measure water quality, such as hydroponics, drinking water, tap water, RO system water, aquarium, seawater, swimming pool water, etc. SPECIFICATION: Temperature Compensation: Automatic Temperature Compensation (ATC) Working Environment: 0 to 60.0 (32.0-140); RH 100% Temperature range: 0.1-60.0 32.0-140 Temperature accuracy: 0.5 Temperature resolution: 0.1/f Automatic shutdown: 5 minutes Battery: 3x1.5LR44 Display size: 33*24mm Size and weight: 183 x 37 x 24 mm SPECIFICATION: Display: Support backlight Waterproof level: IP67 Power consumption: 2.9mA, the power consumption for shutdown is 0 Accuracy within 150 ppt is relatively accurate, and deviation greater than 160 ppt is relatively large.
