Professional 5 in 1 Digital Water Sampler PH/TDS/EC/Salinity/Temperature Measuring Device Pen Waterproof Multifunction Meter

Professional 5 in 1 Digital Water Sampler PH/TDS/EC/Salinity/Temperature Measuring Device Pen Waterproof Multifunction MeterFeatures: Portable TDS Meter can be made anywhere to measure water quality, such as hydroponics, drinking water, tap water, RO system of water, aquarium, seawater, pool water, etc., with high accuracy algorithm chip and electrodes with our digital ph tester to ensure accurate and fast response. Once the measured value is stable, simply press the HOLD/TEMP button to lock the measured value and take it out for viewing, which is really simple. The digital pH tester has the functions of monitoring TDS, pH, salinity, EC meter and temperature measurement. Temperature can affect reading levels, the digital ph meter for water hydroponics has an even better range of 0°c-50°c (32°f-122°f), automatic temperature compensation can ensure you get the best reading, so you can test with confidence in any environment. IP67 is an international waterproof and dustproof certification. Protection against dust intrusion, short-term immersion.
