Selling point:

1. the five-in-one function of this product can measure ph,tds,ec, salinometer and temperature.
2. Measurable salinity (sea salt/fresh water salt)
3. sea Salt: seawater salinity 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 10.1-200.0ppt)
4. 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%)

1. waterproof grade: TP67 (it can still be used when falling into the fish tank)
2. replaceable probe
3. automatic calibration
4. packing specification: 9.5kg, 45*31 * 45cm 50PCs
