The ETS GD10 Gas Detector is a point detector for gas concentration monitoring in potentially hazardous and/or poisonous environments. The ETS GD10 is based on infrared absorption and uses the latest developments in analogue and microprocessor technology. Solid-state design improves reliability, long-term stability and accuracy in continuous measurement of gas concentration in ambient air.

The concept is based on measurement of infrared radiation passing through a volume of gas. The ETS GD10 employs a dual beam, dual wavelength measuring principle with separate optical detectors for maximum stability and reliability.
Since different types of gas have unique absorption spectra, they can easily be identified by proper selection of an infrared wavelength at which absorption is measured. Radiation at another wavelength measures the overall transmission through the optical system and the air volume. By comparing the transmission at the two wavelengths, the gas concentration in the air is determined. Having chosen a wavelength that is characteristic of one type of gas, other types of gas will not cause false alarms.
Using a solid-state IR source instead of a lamp ensures high reliability and long-term stability with no regular maintenance required during equipment lifetime.
