pH/EC/TDS/Temperature meter with HI1285-51 electrode
The HI9812-51 is a portable, water resistant meter designed to be paired with HI1285-51 pH /EC/TDS/Temperature multiparameter probe. The meter is easy to use, with dedicated keys for measurement modes that are clearly displayed on the LCD, and knobs for 1-point calibration of pH and EC. On-screen tutorial messages guide the user through calibration and measurement.
- 3 in 1 probe with pH, EC/TDS and temperature sensors
- Best for hydroponics, greenhouses, farming, and ground water applications
- Large LCD with instructions
The HI9812-51 is a pH/EC/TDS meter for agriculture, greenhouse and hydroponics applications.
These meters feature a large LCD which displays either pH, EC, TDS or temperature readings along with tutorial instructions. The pH readings are displayed with a 0.1 resolution and an accuracy of +/-0.1 pH while the EC and TDS readings are displayed with a 10 mS/cm and 10 ppm (mg/L) resolution and 2% full scale accuracy. The temperature correction coeffcient (β) is fixed at 2 %/°C and allows for automatic temperature compensated measurements of EC and TDS.
These meters are calibrated manually to a single point with the use of two trimmers. pH is calibrated to pH 7.01 while EC/TDS is calibrated to either 1.41 mS/cm (1413 µS/cm) or 1382 ppm. The LCD screen has battery life indicator as well as on-screen tutorial messages.
No probe changes are required when switching your measured parameter between pH, conductivity and TDS. These multiparameter meters reduce the number of instruments required for daily water quality analysis.
