Mobile Biogas analyser H2S CH4 CO2 O2

Mobile Biogas analyser H2S CH4 CO2 O2

GAP 100 allows mobile spot metering. It is used e. g. in renovation work, the exploration of contaminated sites and for the measurement of CH4, CO2, O2 and H2S. As the GAP 100 possesses an integrated data storage, data evaluation on site is possible.

This mobile biogas analyser uses a battery (capacity of up to 8 hours) which makes it easier to work in the field. In addition, these mobile biogas analyser stores the data locally so that it can be read out at a later time. Ideal for people who want to do measurements at multiple locations. The GAP100 only weighs 4.2 kg and easy to move with the handy handle.
