The E300 Pro is the ideal measuring instrument for measuring the electrical conductivity (EC) and temperature of coconut soil and other wet and soft substrates, as well as liquids.

The meter has a modern and robust housing with easy-to-use keys.

The E300 Pro contains an EC electrode of unsurpassed quality.

The measuring device is pre-calibrated and supplied with batteries.

How the device works:

Connect the electrode plug to the EC meter.

Rinse the electrode under running water and dry it with a clean paper towel.

Press the on/off button to turn on the meter.

Place the electrode in the (soft) substrate (and make sure the substrate is well moistened, otherwise the meter will not work properly) or in the liquid to be measured.

Wait for the value to stabilize. The measurement is now complete.

Press the HOLD button to save the measurement. Remember to press the HOLD button again if you want to use the meter again.

Rinse the meter with clean water after use to prevent residue from remaining on the electrode.

Press the on/off button to turn the meter off.
