Substrate pH/Temp S300 Pro 2

The S300 Pro 2 is the ideal meter for measuring pH and temperature of coco soil and other wet and soft substrates and liquids.

The meter has a modern, rugged housing with easy-to-use buttons.

The S300 Pro 2 includes a pH electrode of unprecedented quality.

The meter is pre-calibrated and supplied with batteries.

How the meter works:

Connect the electrode's BNC connector to the pH meter and remove the protective cap with the electrode's storage fluid.

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

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

Place the electrode in the (soft) substrate (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 electrode with clean water after use so that no residue remains on the electrode. Replace the electrode in the protective cap that contains the storage fluid.

Press the power button to turn off the meter.
