The lightweight and easy-to-use Bluelab pH Pen with clear LCD display is designed for pH and temperature measurement. Without cable and temperature compensation. The ideal temperature for perfect operation of the meter is 18-22 degrees.
The Bluelab pH Pen pocket meter is waterproof, powered by only 1x AAA battery. The advantage is the decent dimensions and easy portability and use. We recommend using only Bluelab calibration solutions for calibration.
A flashing light alerts you when the battery is low. Attention, the probe is not replaceable. The instrument is covered by a one-year manufacturer’s warranty against manufacturing defects.
Solutions with pH 4 and 7 are suitable for calibrating the Bluelab pH pen.
