Set 7 In 1 and 5 in 1 PH Meter TDS/EC/Salt/Temp Water Quality Monitor Tester Pen

Feature:
Multi-functional water quality test pen, which can measure ph pH, solubility, EC conductivity, salinity and temperature. (Sea salt/fresh water salt)
It is a waterproof water quality test pen with five functions. It has high performance, pen design and fast numerical value.
Parameters:
Sea salt: Sea water salinity is the ratio of total dissolved solids to the weight of sea salt in sea water, usually expressed in grams per kilogram of sea water. (Measuring range 10.1-200.0ppt)
