What the Meter Reads and How It Is Built
10-in-1 Multi-Parameter Meter
One pen covers ten water parameters, including pH, TDS, EC and salinity. You dip the probe once and read the values on the display, which keeps the bench or toolbox free of separate testers.
Hydroponic Nutrient Mode
A dedicated mode shows EC and salinity readings for nutrient reservoirs. Growers use the numbers to adjust their mix and to keep track of how the solution changes between top-ups.

Glass-Free Construction
The probe design has no fragile glass element, and there is no sample prep step. The pen is carried in the protective case, which suits field use around tanks, pools and garden reservoirs.
Thermal Compensation
A built-in sensor adjusts readings for water temperature across a range of 0-60°C. The meter applies the correction automatically while it measures, so you do not enter a temperature by hand.

HydroSage Pro is a salinity meter built as a 10-in-1 pen that reads pH, TDS, EC and salinity from a single dip. It is made for people who check water in several different places.
Used as a digital salt meter for pools, it fits routine saltwater pool checks. As a salt tester it also covers freshwater tanks, saltwater setups, sumps, hydroponic reservoirs and drinking water. A hydroponic nutrient mode tracks EC and salinity for garden reservoirs.
To use this digital salinity meter, rinse the probe tip, dip it into the sample and press one button. A built-in sensor provides automatic thermal compensation from 0-60°C, and the result shows on the digital display.
