Amphenol SGX Sensortech SGX-7x Electrochemical Sensors are industrial and commercial gas sensing modules that detect gasses such as chlorine, carbon monoxide, nitric oxide, nitrogen dioxide, ammonia, hydrogen sulfide, sulfur dioxide, and oxygen. These SGX-7x sensors offer an operating temperature range of -30°C to +50°C and a 15% to 90% RH humidity (non-condensing) range. Amphenol SGX Sensortech SGX-7x Electrochemical Sensors are available in an industry-standard 31.5mm diameter package and are ideal for fixed devices. Typical applications include oil and gas, petrochemicals, steelworks, wastewater, and indoor air quality.
