New Cosmos KD-12 Series product image

Fixed Gas Detector for All Gases, with Display and Stainless Steel Enclosure

The New Cosmos KD12 is used to detect leaks or deficiencies of oxygen, methane and carbon dioxide, as well as many explosive gases. The New Cosmos KD12 displays the concentration of the target gas and outputs an analogue signal between 4-20 mA DC representing this concentration to an external device. When a set concentration is reached, the red lamp and alarm relays activate, making the New Cosmos KD12 an ideal device for monitoring gas concentrations.

Maintenance is vital for the trouble-free operation of Gas Detection and Alarm systems. Always take care to ensure the maintenance and calibration of your instrument.

    Gas Detection and Standards Approach

    Gas detection approach: Gas type, target measurement range, alarm purpose, sampling/diffusion method, sensor principle and site atmosphere must be evaluated together. In oxygen measurements EN 50104; in toxic gas applications the EN 45544 series; in combustible gas and explosive atmosphere applications the EN/IEC 60079 series may be relevant. These statements do not imply that the model is certified to all standards; exact compliance must be confirmed separately according to model code, target gas, and certificate version.
