Overall, the AquaMaster E300 Pro Substrate EC/Temp Meter is an effective, efficient, and reliable tool for managing plant health and achieving optimal yields. Whether you are a professional grower or a hobbyist, the AquaMaster E300 Pro is an indispensable tool for measuring EC and temperature in soil and hydroponic systems.

  • Connect the PIN connector of the electrode to the EC meter
  • Rinse the electrode with running water and dry it using clean kitchen paper
  • Press the on/off button to turn on the meter
  • Place the electrode in the (soft) substrate (make sure the substrate is well wet/damp, otherwise the meter will not work properly) or liquid to be measured
  • Wait for the value to stabilise. The measurement is now complete
  • Press the HOLD button to save the measurement. Do not forget to press the HOLD button again when the meter is used once more
  • Rinse the electrode with clean water after use, so that no residue is left on the electrode
  • Press the on/off button to turn off the meter
