Error message when trying to calibrate? This should help!
Calibrating Bluelab pH Probes and Meters is simple, and the process should be very similar across our full range of products.
The following video shows how to clean and calibrate a Bluelab Combo Meter and pH Probe.
The information does still apply to other products such as the Bluelab Guardian Monitor or pH Controller, which have the same probe cleaning and maintenance requirements as the Combo Meter.
