SMART SENSOR PH Temperature TDS EC Salinity Meter Digital Waterproof With Automatic Calibration Function Water Quality PH Tester

water quality impact, and a high-precision PH meter can be solved.IP65 Waterproof: IP65 waterproof and moisture-proof design, even if dropped into the water or solution as soon as possible to salvage can be normal measurement use.Over-Range Alarm: When the pH value is lower than 3.5 or higher than 12.5 pH, the screen will turn red, indicating that the liquid is close to a strong acid or base.Automatic Temperature Compensation: The temperature of the instrument will have a certain impact on the pH measurement, and the impact will be even greater if the precision requirements are high, so the temperature compensation function is very necessary.LCD HD Color Display: The color screen is not blinding can easily deal with the dark environment at night, while displaying the water salinity value and temperature data.Lithium Direct Charging: USB lithium direct charging, support a variety of charging methods.Widely Used: The pH value is closely related to our daily life, for example, carbonated
