5 in 1 TDS/EC/PH/Salinity/Temperature Meter Digital Water Quality Monitor Tester for Pools, Drinkin f26 [5-in-1 Water Quality Tester]Digital pH tester has the functions of monitoring TDS, pH, salinity, EC meter and temperature measurement. TDS measurement range: 0-1000ppm, EC measurement range: 0-10000US / cm, PH measurement range: 0.01-14.00pH, salinometer measurement range: 0.00-25.00%, temperature conversion function. [High Accuracy]High-accuracy algorithm chip and electrode of our digital water ph tester an accurate and fast response. When the measured value is stable, just press the HOLD/TEMP key to lock the measured value and take it out for viewing, which is really simple. [Two Salinity Meters]Digital PH meter can detect the salinity of edible salt. At the same time, it can detect the salinity of seawater. Food salinity measuring range: 0.00-25.00%, seawater salinity measuring range: 10.1-200.0ppt. [Automatic power-off function & large screen display]PH tester has a backlight LCD that helps you clearly see the measurement in any case. The automatic power-off function turns off the power after 5 minutes without any operation to save power. Employs a fully transparent liquid crystal (LCD) to display 4-digit values and the corresponding physical quantity units. [Automatic Temperature Compensation]Temperature can affect reading levels, Digital PH Meter for water hydroponics has an even better range of 0 C-60 C (32 F-140 F), automatic temperature compensation can that you are the best reading, so you can test with confidence in any environment.
