Abstract:
1. An H2S monitor for monitoring an atmosphere, wherein the atmosphere includes a sample of gas flowing, migrating or otherwise traveling in an approaching flow direction toward the H2S monitor, the H2S monitor comprising: a housing defining an exterior, an interior and an opening through the housing; a hydrogen sulfide sensor disposed within the interior of the housing in proximity with the opening; a moisture sensor being supported by the housing in proximity with the opening, the moisture sensor, with respect to the approaching flow direction, being upstream of the hydrogen sulfide sensor, wherein the atmosphere contains moisture exposed to the moisture sensor; a predetermined moisture alarm threshold associated with the moisture sensor; and a moisture alarm emitted in response to the moisture sensor sensing that the moisture exceeds the predetermined moisture alarm threshold, the predetermined moisture alarm threshold being such that a predetermined amount of liquid water contacting the moisture sensor exceeds the predetermined moisture alarm threshold, and the atmosphere at 100 percent relative humidity is in itself less than the predetermined moisture alarm threshold.
