Waterproof Dependent Gas Detectors

GAS SENSOR Benchtop gas detection unit with power, alarm, and fault indicators.

Olympia Electronics Waterproof Gas Detectors: Reliable Methane, LPG & CO Detection

This range of waterproof gas detectors includes models for detecting natural gas (methane), LPG (propane), and carbon monoxide. Built for fixed installation, they are suitable for commercial kitchens, garages, basements, burner rooms, and light industrial spaces. Each unit features a durable IP65 or IP66-rated housing that withstands harsh environments. The detectors provide visual and relay-based alarm outputs for prompt gas leak alerts and can easily integrate with fire and gas systems. Depending on configuration, catalytic or electrochemical sensors ensure reliable, precise detection. Correct placement and calibration ensure optimal safety and compliance.
