Sale price£304.50


The HI-9814 is a lightweight, waterproof portable pH, conductivity, TDS and temperature meter supplied with a specialist multiparameter probe designed for hydroponics, greenhouse and agricultural applications.

  • Compact, robust casing
  • Simultaneous readout of pH, EC or TDS and °C
  • Simple two-button keyboard
  • Waterproof design to withstand the humidity of a growing environment
  • Specialist multi-parameter electrode
  • Optional green protective rubber holster - HI-710025

The HI-9814 boasts many advanced features that are usually found in more expensive portable meters, including automatic calibration, buffer/standard recognition and temperature compensation. On-screen tutorial messages and indicators for the calibration status and stability can be viewed on the large multi-level LCD display.

What you get:

  • HI-9814 is supplied with HI-1285-7 multi-parameter probe
  • HI-50036 Quick Cal buffer solution sachet (3)
  • HI-700661 pH electrode cleaning solution sachet for agriculture (3)
  • 1.5 AAA batteries (3)
  • Instructions and instrument quality certificate

The HI-9814 is supplied complete with the HI-1285-7 specialist electrode that features the following key benefits:

  • Pre-amplified pH electrode - prevents interference from humidity and sources of electrical noise including circulating pumps, motors and ballasts from grow lights.
  • Amperometric EC/TDS sensor - EC/TDS readings are performed by a two-pin amperometric sensor, best suited to low conductivity applications
  • Built-in temperature sensor - readings of pH and EC/TDS must be temperature compensated in order to obtain accurate results. The built-in temperature sensor provides a speedy temperature reading which is then used to adjust the pH and EC/TDS results accordingly for higher accuracy.
  • Polypropylene body - the durable body of the HI-1285-7 electrode is chemically resistant to many aggressive chemicals used in hydroponics and protects all three sensors.
  • DIN Connector - the HI-1285-7 has been specifically designed for use with the HI-9814 meter, the DIN connector means the probe is not interchangeable.
