Abstract
An H2S (hydrogen sulfide) monitor includes a hydrogen sulfide sensor and a moisture sensor. In some examples, the H2S monitor emits a moisture alarm if the moisture sensor detects liquid water in an amount that exceeds or approaches a moisture tolerance limit of the hydrogen sulfide sensor. In some examples, the moisture sensor prevents the hydrogen sulfide sensor from triggering a false H2S alarm caused by moisture contaminating the hydrogen sulfide sensor.
