Calibrating your Bluelab pen
Calibrate for accuracy
To ensure ongoing accuracy, you should calibrate your pH pen on a regular basis. Fortunately, with Bluelab, calibration is quick and straightforward.
Calibration is a two-step process. First, clean your pH pen and then calibrate to two pH points using Bluelab pH buffer solutions (pH 4.0 and 7.0). The on-screen information will guide you through the process. Once complete, the calibration symbol will appear on your screen.
You should recalibrate whenever the calibration symbol disappears or after cleaning your pen. If you take daily measurements, you’ll need to calibrate more frequently.
Our conductivity pens are factory calibrated and won’t need further calibration; however, you should clean your pen regularly.
