How to calibrate your Bluelab meter
Easy calibration for ongoing accuracy
If your Bluelab meter comes with a pH probe, you will need to calibrate it to ensure ongoing accuracy. With Bluelab, the calibration process is quick and straightforward.
You can calibrate in two steps. Take your clean pH probe and calibrate to two pH points using Bluelab pH buffer solutions (pH 4.0 and 7.0). Your meters' on-screen information will guide you through the process. Once complete, the calibration symbol will appear on your screen.
For other parameters, including conductivity and temperature, our digital meters are factory calibrated and will not need to be calibrated again. However, we do recommend that you clean your probes regularly.
Meter maintenance
Caring for your digital meter
For maximum efficiency and accuracy, you should clean your meter’s probes on a regular basis. All Bluelab products come with easy-to-follow care instructions. To make it even simpler, you can purchase our care kits, which contain everything you need to clean your meter’s conductivity and pH probes.
Our fuss-free care kits contain probe cleaner, cleaning tools, calibration solutions and much more. Simply follow the step-by-step care guide that accompanies your digital meter. You will need to calibrate after cleaning your pH probe. Once cleaning and calibration are complete, you can start measuring with optimal accuracy again straight away.
