HI-9812-5N is a versatile, water resistant multi-parameter portable meter specifically designed for agricultural applications such as hydroponics, greenhouses, farming and nurseries. It features an extra large LCD that clearly displays the parameter being measured as well as calibration instructions.

HI-9812-5 pH/EC/TDS/°C Portable Meter information

Hanna's extended description

Portable pH/EC/TDS/Temperature meter



The HI-9812-5 is a pH/EC/TDS water resistant meter designed for simplicity in taking pH, µS/cm, ppm (mg/L) and temperature measurements. The HI-9812-5 is ideal for hydroponics, greenhouses, farming and ground water applications.


Due to the built-in temperature sensor, conductivity readings are automatically compensated for temperature changes. No probe changes are required when switching your measured parameter between pH, conductivity and TDS. These multi-parameter meters reduce the number of instruments required for daily water quality analysis.


The specially engineered HI-1285-5 pH/EC/TDS and temperature probe utilises a fibre junction and gel electrolyte which provide a fast response and reduced contamination. This combination makes the HI-1285-5 particularly designed to withstand harsh environments such as fertiliser solutions.


Key features


  • Water resistant
  • On-screen tutorial messages for calibration
  • BEPS (Battery Error Prevention System) alerts the user in the event that low battery power could adversely affect readings
  • Switch parameters at the touch of a button
  • Automatic Temperature Compensation for pH and conductivity
  • Simple calibration
  • Battery % displayed on start-up
  • Fast response multi-parameter probe



Replaceable Electrode – No need to replace the whole meter when the electrode needs replacing. Spare and replacement electrodes are available for this product.



Water Resistant – Can withstand temporary exposure to water, but should not be submerged or washed under running water.
