Aqua Master Substrate EC/Temp E300 Pro The E300 Pro is the perfect tool for measuring the EC and temperature of coconut soil, as well as other moist, soft substrates and liquids. Featuring a modern, durable design with user-friendly controls, the E300 Pro comes equipped with a high-quality EC electrode. It is delivered fully calibrated and includes batteries for immediate use. How to use the meter: Connect the electrode’s PIN connector to the EC meter. Rinse the electrode with running water and dry it with clean kitchen paper. Press the power button to turn on the meter. Immerse the electrode into the (soft) substrate (ensure the substrate is sufficiently wet or damp, as dry substrates will affect accuracy) or liquid you wish to measure. Wait for the reading to stabilize. Once it does, the measurement is complete. Press the HOLD button to store the reading. Remember to press HOLD again when you are ready to take another measurement. After use, rinse the electrode with clean water to remove any residue. Turn off the meter by pressing the power button.
