Introduction

This simple device uses and electochemical sensor to measure the oxygen concentration in gas mixtures and air. The opening of the sensor allows the local air to diffuse into the sensor. The unit can be calibrated in fresh air (atmospheric oxygen concentration is 20.59%.)The reading is automatically compensated for temperature. The reading needs to be compensated for air pressure and this can be done during calibration by entering the local air pressure on the keypad.
