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

How does the tester work?

• Connect the BNC connector of the electrode to the pH tester 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 tester
• Place the electrode in the (soft) substrate (make sure the substrate is well wet/damp, otherwise the tester 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 tester 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 tester

We recommend storing the tester with KCI storage solution in the protective cover.
