Unlock the full potential of your Bluelab pH Pen with these simple steps. Begin by soaking the pen in a potassium chloride solution for 24 hours before calibrating it. To ensure accurate readings, recalibrate weekly by moistening the probe and immersing it in calibration fluid. Switch effortlessly between Celsius and Fahrenheit with the ‘units’ button.

Before each use, rinse the probe, turn on the meter and immerse the probe in the nutrient solution. Within seconds, capture your pH measurement and use pH Up or pH Down adjustment fluids for corrections. Turn off the meter by holding the power button for 3 seconds and rinse the probe after use to replace the end-cap.

Remember to exercise caution and proper handling when using pH adjustment fluids. Upgrade your measurements with the Bluelab pH Pen – the simple and efficient way to monitor pH levels.
