CO-measuring device with alarm

HIGHLIGHTS:

• 3 display units selectable (ppm, mg/m³ and % CO Hb)
• Alert at exceeding the maximum concentration at work (MAK/AGW)
• incl. interface
• incl. calibration protocol

GENERAL:

Carbon monoxide (CO) is created by the combustion of carbon. Depending on the effectiveness of the combustion (oxygen supply) and the temperature of the combustion more or less CO gas is created. The gas is inflammable and highly toxic. It is invisible, tasteless and scentless.
Even smallest concentrations are dangerous for humans!
Therefore a directive exists in Germany, which limits the maximum concentration of CO gas at work (MAK / AGW) to 30 ppm.

APPLICATION:

• Control of the air quality (e.g. at work place)
• Checking of heating systems, gas central-heating, fireplace
• Control of the air at maintenance work (tunnel, flue gas tract, ...)
• Detection of CO in the breath of smoker (% CO Hb)
• Cognition of CO poisoning i.e. at burnt offering (fire fighters, ...)
