Everything you need to clean, hydrate and calibrate pH probes as well as clean and test conductivity (ppm/EC) probes

The instrument is only as accurate as the probe is clean. Accurate readings simplify water management and provide improved growth.

Probe cleaning and correctly storing pH probes ensures you get the most accurate readings possible and will maximise the life of a probe.

The probe surface is where the instrument takes the reading of the solution. If the probe face is dirty or contaminated, the readings may be inaccurate. If the probe face is dirty, it cannot read the solution accurately.

A tip… if the conductivity reads low, the probe needs cleaning. pH probes specifically, should be kept wet at all times for optimal performance and life.
