Why Choose Our HM Digital AP-2 AquaPro

Unlike basic testers that show only conductivity, this electrical conductivity tester displays EC and temperature simultaneously. Digital calibration removes the need for screwdriver adjustment, while the magnetic body offers convenient storage. It measures EC, not pH, TDS or specific contaminants.

Perfect For

RO filter checks, tap water, hydroponic nutrients, aquariums, pools, spas and general water monitoring.

How to Use

Remove the cap, switch on and immerse only the sensor end in the sample. Stir gently, wait for a stable result and press HOLD if needed. Rinse the electrodes after testing; never fully submerge the housing.
