Portable 5 in 1 Pen Type Digital Water Quality pH/Salinity/TDS/EC/Temperature Meter Tester with Backlight Waterproof Measurement Detection Water Purity Monitor
5 in 1 function, can measure pH, TDS, EC, salinity meter and temperature.
Measurable salinity (sea salt/fresh water salt).
Sea salt: Seawater salinity is the ratio of total dissolved solids to the weight of sea salt in the seawater, usually expressed in grams per kilogram of seawater. (Measuring range 10.1-200.0ppt)
Light salt: light water with a salt content of less than 0.5g/L (measurement range: 0.00-25.00% accuracy: 0.01-5.00% 5.10-25.00%).
The probe can be replaced.
Automatic calibration.
