Biogas Analyzer System

SKU: Biogas

Avensys has designed and integrated the famous Awite AwiFlex Cool+ XL to provide an easily deployable and scalable BIOGAS Analysis solution with a minimal footprint. This system is ideal for use in any application that requires the measurement of air, biogas, sewage gas, biomethane, oxygen as well hydrogen sulphide. The basic configuration includes five measuring sensors that can be used for each sample point.
The System comes ready to use – all you need to do is connect the sample probes to your sample lines. You can install the system in any container or on a structural wall. Our solution comes pre-mounted on a selfstanding metal rack for easy deployment.
