Theory of operation
The Santacary XAR-HP H2S Gas Detector uses 3-electrode electrochemical technology, operating by the diffusion principle, for determining the concentration of H2S in air samples. In diffusion mode, the atmosphere reaches the sensor in the front end of gooseneck by diffusing. Normal air movements are enough to carry the sample to the sensor.

Alarm
Low Alarm and High Alarm
XAR-HP has two alarm set points: High Alarm (H2S: 15 PPM) and Low Alarm (H2S: 10 PPM).These set points are factory set and cannot be changed. XAR-HP is equipped with audio alarms to alert you when the ambient gas concentration exceeds one of the two alarm set points. When H2S value exceeds the defined high alarm set point (15 PPM), the audio alarm will sound at 6 beeps/sec. When H2S value exceeds the defined low alarm set point (10 PPM) but less than the defined high alarm set point (15 PPM), the audio alarm will sound at 4 beeps/sec.
