EC4 Electrochemical Gas Sensors

Amphenol SGX Sensortech EC4 Electrochemical Gas Sensors feature 20mm and 20.2mm package sizes and act as drop-in replacements for existing same-size sensors. The EC4 series is available in a broad range of sensing types to detect toxic gases: sulfur dioxide (SO2), carbon monoxide (CO), hydrogen (H2), chlorine (Cl2), hydrogen sulfide (H2S), chlorine dioxide (ClO2), nitric oxide (NO), nitrogen dioxide (NO2), ethylene oxide (C2H4O), and phosphine (PH3). Amphenol SGX Sensortech EC4 Electrochemical Gas Sensors are low power and show good responses to various gas concentrations over a wide range of ambient conditions.
