Single H₂S detector is an intrinsically safe and explosion-proof instrument and is designed to deter H₂S.

Single H₂S detector is a low-cost, maintenance-free single gas monitor designed to protect personnel from dangerous H₂S gas exposure in the most extreme conditions. Despite its compact size, the single H₂S detector includes features usually found only in larger multi-gas monitors including a large, OLED display, internal audible/visual alarms and simple push-button operation.

The monitor continuously displays ambient combustible gas readings and will alert the user when gas concentrations exceed the preset low or high levels. Added features include adjustable alarm setpoints, calibration gas values, and choice of text-only display selected by the user through a simple, push-button routine. Single H₂S detector also has a peak/hold feature to show the highest reading during a shift and includes a special flip-cap calibration adapter for quick and simple calibration.
