Theory of operation
The Santacary XAR-AP Ammonia Gas Detector uses 3-electrode electrochemical technology for determining the concentration of ammonia 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-AP has two alarm set points: High Alarm (NH3: 50 PPM) and Low Alarm (NH3: 25 PPM).These set points are factory set and cannot be changed. XAR-AP is equipped with audio alarms to alert you when the ambient gas concentration exceeds one of the two alarm set point. When Ammonia value exceeds the defined high alarm set point (50 PPM), the audio alarm will sound at 6 beeps/sec. When Ammonia value exceeds the defined low alarm set point (25 PPM) but less than the defined high alarm set point, the audio alarm will sound at 4 beeps/sec.
Factory Alarm Set points
Gas | Low | High |
NH3 | 25 PPM | 50 PPM |
Gooseneck pipe
With the sensor placed at the front end of the gooseneck, XAR-AP is able to monitor the NH3 concentration quickly in inaccessible or dangerous places. XAR-AP is also able to detect the leakages of NH3 gas.
