HI 9812-0 and HI 9812-5 are easy to use portable instruments for field measurements of pH, conductivity and TDS in water conditioning applications. Reduce your necessary tool set for field water-quality analysis. HI 9812-0 measures pH from 0.0 to 14.0. This meter also checks conductivity and TDS from 0 to 1990 mg/L, ideal for the water conditioning field. Calibration has been simplified to one point for both pH and conductivity/TDS modes.

Both HI 9812-0 and HI 9812-5 are equipped with Automatic Temperature Compensation to remove the effects of temperature on your conductivity and TDS measurements. In addition, the BEPS (Battery Error Prevention System) will alert the user when low batteries could affect the readings.

HI 9812-0 uses HANNA® 4-in-1 replaceable HI 1285-0 probe, while HI 9812-5 uses HI 1285-5. No probe changes are required when switching your measured parameter between pH, conductivity and TDS.

Specifically engineered for water-quality applications, the pH electrode features a fiber junction and gel electrolyte that provides faster response and reduced contamination.

Finally, HI 9812-5 also measures temperature in °C.
