Selling point:

1. This product has a five-in-one function that can measure pH, TDS, EC, salinity, and temperature.
2. Salinity (Sea Salt/Freshwater Salt)
3. Sea salt: The salinity of seawater is the ratio of total dissolved solids to the weight of sea salt in seawater, usually expressed in grams per kilogram of seawater. (Measurement range: 10.1-200.0 ppt)
4. Light Salt: Contains less than 0.5g/L of salt in the water (measurement range: 0.00-25.00% accuracy: 0.01-5.00% 5.10-25.00%)

1. Waterproof rating: TP67 (Can still be used even if it falls into a fish tank)
2. Replaceable probe
3. Autocalibration
4. Packing Specification: 9.5KG, 45*31*45cm, 50pcs
