An Analysis of the H2S MOS Sensor Performance Myth

Tyco Gas and Flame Detection

H2S MOS sensors have gained a reputation for being susceptible to sensitivity loss, sometimes at alarmingly rapid rates.

The truth is that some solid state sensors will degrade in sensitivity at such a pace that from one calibration interval to the next, it appears as though the sensor has completely lost its sensitivity to scale.

In many of these compromised cases, it was found that repeated high doses of H2S could temporarily recover some of the lost H2S sensitivity, implying that it had 'gone to sleep' because it appeared that 'it could partially be woken up'.
