GD10P CO2 Infrared Gas Detector

General Details


The GD10P-CO2 has been designed with features that provide an effective response to the detection of CO2 in a wide range of industrial environments from boiler plant rooms to offshore petrochemical installations.
The GD10P-CO2 differs from all other point infrared gas detectors, because they utilise silicon based solid-state sources. 
The complete optomechanical design and construction is so stable that an ultra fast speed of response can be achieved whilst providing unparalleled service life and detector stability, thus saving on maintenance and service costs.
We offer the longest combined detector and IR source warranty on the market.
Supplied with worldwide hazardous area approvals. Suitable for use in SIL 2 systems.
An industry standard HART® interface is used for configuration of special fault levels as well as access to extended maintenance data.
