Selling point:

This product has five functions in one, which can measure ph, TDS, ec, salinometer and temperature

Measurable salinity (sea salt/fresh water salt)

Sea salt: the salinity of sea water is the ratio of the total dissolved solids to the weight of sea salt in sea water, usually expressed in grams per kilogram of sea water.(measurement range 10.1-200.0 PPT)

Light salt: light water with salt content less than 0.5g/L (measurement range: 0.00-25.00% accuracy: 0.01-5.00% 5.10-25.00%)

Waterproofing rating: TP67 (can still be used if dropped into the tank)

Replaceable probe

Automatic calibration
