BG20 carbon monoxide measuring device

For quick checking of CO concentrations

Quick and reliable measurement of CO concentrations in the ambient air

With the BG20 of the MultiMeasure Basic series, the exact CO content in the ambient air can be detected and so one can e.g. ensure the adherence to applicable limit values at the workplace.

The hand-held measuring device is ready for operation a few seconds after switch-on and quickly and reliably captures CO concentrations ranging from 0 to 1,000 ppm. The values are determined accurately to ± 10 ppm and indicated clearly legible on the large, backlit display. If required, ten measured values can further be stored directly in the BG20.

Thanks to the integrated alarm function, it is also very simple and convenient to quickly check critical values: In case of values above 35 ppm, the measuring device automatically alerts the user by means of an acoustic signal, whose interval shortens with increasing values and from 200 ppm is emitted as a constant warning signal.

Thanks to the automatic switch-off after 15 minutes of inactivity, unintentionally flat batteries have become a thing of the past.

The clearly structured function keys allow convenient single-handed operation.

Facts worth knowing about carbon monoxide:

Carbon monoxide (CO) is an invisible, odourless and tasteless gas forming in the process of combustion of fossil fuels. Without a sufficient oxygen feed, the CO concentration in the ambient air rises especially fast and then even small amounts can be enough to cause damages to health:

Already at a CO share of only 1.28 % in the room air, death by suffocation occurs after only one to two minutes.

Therefore, in Germany we have severe limit values required by law for the CO exposure of employees. The permissible limit value here is 30 ppm (corresponds to 35 mg per m³) in the ambient air.

Nevertheless, the air pollution in production facilities, craft enterprises or workshops is often wrongly assessed and the risk of CO poisoning ignored, although even the short-term operation of diesel-powered and petrol-driven machines in closed rooms such as underground car parks, assembly shops or construction sites can lead to symptoms of intoxication.

Hence, it is important to constantly check the current CO concentration in indoor spaces, factory halls and building sites using appropriate measuring devices. The inspection of the air quality by use of CO measuring devices is also absolutely recommendable for the catering trade, e.g. when using gas radiant heaters, or for indoor go-kart operators.
