1GA 50916/CHCO
Wall-mounted carbon monoxide (CO) and natural gas (CH4) detector
The detector can detect two gases: natural gas (CH4) and carbon monoxide (CO)
Intervention sensitivity:
- natural gas at 10% of the lower explosion limit
- carbon monoxide, when the maximum allowed 300ppm CO concentration is exceeded, or rather in case low but damaging concentrations 30ppm for 2 hours persist for long periods in the premises.
