Prices include GST. Not all items are in stock. Call 03 9769 0666 to confirm.

pH/EC/TDS/Temperature meter with HI1285-51 electrode; EC range: 0 to 6000 µS/cm, TDS range: 0 to 3000 ppm (mg/L).

The HI9811-51 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 combination probe with pH, EC /TDS, and temperature sensors
  • Best for agriculture, greenhouse, and hydroponics applications

Description

The HI9811-51 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 coefficient (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.

The supplied probe on all models features a polypropylene body, an amplified pH electrode with a built-in EC/TDS, and temperature sensors. The amplifier for the pH electrode prevents interference from humidity and electrical noise from common sources including from motors, ballasts, or pumps.
