pH/EC/TDS Meters for Water Conditioning
- Measure pH, conductivity and TDS simultaneously
- Fast response probe
- Automatic temperature compensation
HI 9812 and HI 9812-5 are easy to use portable instruments for field measurement of pH, conductivity and TDS in water conditioning applications. These powerful instruments 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 instruments 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. The specially engineered pH electrode also features a fiber junction and gel electrolyte for faster response and reduced contamination. Finally, HI 9812-5 also measures temperature.
HI 9812 is supplied complete with pH/EC/TDS probe, HI 1285-0 with 1 m cable, pH 7 calibration solution (1 x 20 mL), 1382 ppm and 1413 µS/cm calibration solutions (1 each), cleaning solution (2 pcs), blue protective case, battery and instructions. HI 9812-5 is supplied complete with pH/EC/TDS/T HI 1285-5 with 1 m cable, pH 7 calibration solution, 1382 ppm and 1413 µS/cm calibration solution (1 each), cleaning solution (2 pcs), blue protective case, battery and instructions.
