The S300 Pro 2 is the ideal meter to measure the pH and temperature of coconut soil and other moist, soft substrates and liquids. The meter features a modern and robust housing with easy to operate buttons. The S300 Pro 2 includes a pH electrode of unprecedented quality. The meter is delivered fully calibrated and includes batteries.

Connect the BNC connector of the electrode to the pH meter and remove the protective cap containing storage solution from the electrode.
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. Replace the electrode in the protective cap containing the storage solution.
Press the on/off button to turn off the meter.
We recommend storing the meter with KCI storage solution in the protective cover.
