BCP-CH4 analyzers are suitable for measuring methane in biogas applications or process development with methanogenic or methanotrophic organisms. BCP-CH4 gas sensors can be used in any scale of biogas process from lab to industrial scale digesters and all scales of industrial microbiology processes from lab to manufacturing scale. Data transfer to process control systems is simple. BCP-CH4 can be used directly on the gas stream with no requirements for pretreatments. All BCP-analyzers are available with aluminium (pilot to industrial scale use) or PA (lab scale) casings. BlueSens offers the Yieldmaster series for customers interested in BMP (bio methane potential) determinations.

BlueVary – for 100% flexibility

BlueVary is a maintenance free gas analyzer for variable applications. By freely selectable sensor cartridges different measuring tasks can be covered by just one device.

BlueVary consists of a basis element with measurement places for two of the variable gas sensor cartridges. That way two gases can be measured in parallel. The third place holds a sensor cartridge for pressure and/or humidity. An integrated display ensures insight of the measured data at any time. Various mechanical connections make BlueVary fit on every fermenter. Numerous data output possibilities are available. Annual maintenance is unnecessary. To maintain accuracy of the readings a one-point calibration has to be performed (by the user) in reasonable time intervals.
