Page 3: Introduction
Congratulations on your purchase of this ESSAN-20 Pocket Personal Safety O2 Monitor. The ESSAN-20 is a personal safety O2 monitor designed to monitor ambient oxygen levels in real time. It is designed to protect workers in confined spaces. ESSAN-20 is shipped fully tested and factory calibrated and, with proper use, will provide years of reliable service. -
Page 4: Theory Of Operation
THEORY OF OPERATION The ESSAN-20 Personal Safety O2 Monitor determines the concentration of oxygen in air samples using the principle of fluorescence quenching by oxygen. Air reaches the sensor by diffusing through the openings of the unit. Normal air movement is enough to carry the sample to the sensor. -

OPERATION 1. Power button 1) When the Monitor is turned off, press to turn on the unit. 2) When the Monitor is turned on, press for 3 seconds to turn off the unit. When the unit is first turned on, it performs 5 seconds countdown for Monitor warm up, then enters normal display with current O2, temperature, and humidity readings displayed. - Page 6 "IP" during the calibration. 4. Alarm Threshold There are high and low alarm thresholds in ESSAN-20. Both high and low alarm has twelve thresholds: 15.0%, 15.5%, 16.0%, 16.5%, 17.0%, 17.5%, 18.0%, 18.5%, 19.0%, 19.5%, 23.0%, and 23.5%.
