【5-in-1 Water Quality Tester】The digital pH tester has the functions of monitoring TDS, pH, salinity, EC, and temperature. 【High Precision】The high-precision algorithm chip and electrodes of our digital water pH tester ensure accurate and fast response. When the reading is stable, simply press and hold the HOLD/TEMP button to lock the reading and output the display, which is very easy. 【Dual Salt Meter】The digital pH tester can detect the salinity of food. At the same time, it can detect the salinity of seawater. Measurement range of table salt content: 0.00-25.00%, measurement range of seawater salinity: 10.1-200.0 ppt.

【Automatic Shutdown Function and Large Screen】The pH tester has a backlit LCD screen, allowing you to clearly see the measurement results in any circumstances. The automatic shutdown function turns off the device after 5 minutes of inactivity to save power. A fully transparent liquid crystal (LCD) is used to display 4-digit values and corresponding physical units. 【Automatic Temperature Compensation】Temperature affects the reading; the digital hydroponic pH meter has a better range from 0°C to 60°C (32°F to 140°F). Automatic temperature compensation ensures you get the best readings, allowing you to test safely in any environment. Specification:
