Multi-Parameter Meters

• Measure three parameters with one versatile meter.

Measure pH, conductivity and TDS at the same time and reduce the number of instruments you take into the field. No probe changes are required when switching between these parameters using the newly designed four-in-one replaceable HI 1285 probe. The probe utilizes a temperature sensor to provide readings that are automatically compensated for temperature. The pH electrode features a fiber junction and gel electrolyte for faster response and reduced contamination. Two models are available and both measure pH from 0 to 14 with 0.1 resolution. HI 9812 checks conductivity and TDS in the lower 0 to 1990 ranges, while HI 9811 measures conductivity from 0 to 6.00mS/cm and TDS from 0 to 3.00g/L both in hundredths of units.

Powered by a 9V battery (included), the meters are equipped with BEPS (Battery Error Prevention System) to avoid errors due to low battery power. Battery provides approximately 150 hours of continuous use.

Meters are sold complete with the HI 1285 probe with 1m cable, pH 7 buffer (20mL), 1413µS/cm and 1382ppm calibration solutions (20mL each), 9V battery and instructions. 7.3" x 3.2" x 1.8".
