The Simple Diffusion 2-Year Multi-Gas Detector is a compact, low-maintenance unit designed for continuous passive monitoring of hydrogen sulfide (H₂S), carbon monoxide (CO), oxygen (O₂), and combustible gases (LEL).
It offers a two-year operational lifespan without the need for external power, calibration, or maintenance.
This gas detector uses passive diffusion sampling to continuously “sniff” ambient air and trigger alarm warnings if any of the monitored gas levels exceed preset safety thresholds.
The rugged housing is made to provide you with durability, and a clearly visible multi-color alert indicator (LED or dial, depending on model) provides immediate response.
