SGX-4x Electrochemical Sensors

Amphenol SGX Sensortech SGX-4x Electrochemical Sensors are available in a broad range of sensing types for industrial and commercial gas applications. These air quality sensors allow instrument manufacturers a greater choice when selecting sensors for carbon monoxide (CO), hydrogen sulfide (H₂S), oxygen (O₂), ammonia (NH₃), chlorine (Cl₂), multi-gas nitric oxide (NO), nitrogen dioxide (NO₂), and sulfur dioxide (SO₂). These sensors have a minimum operating temperature of -40°C, -30°C, or -20°C, and a maximum operating temperature of +50°C or +60°C. Amphenol SGX Sensortech SGX-4x Electrochemical Sensors are available in 20mm industrial standard packages and act as drop-in replacements for existing sensor types in this size.
