DP-28 BIO Portable biogas analyzer




DP-28 BIO is a series of modern portable analyzers of biogas composition, allowing for the qualitative analysis of the mixture resulting from methane fermentation.

The DP-28 BIO series portable analyzers can be supplied with various sensor operating ranges (Methane, Carbon Dioxide, Oxygen and Hydrogen Sulphide) depending on the requirements of the recipient and the type of biogas plant on which the device is to operate.


DP-28 BIO is a portable modern device designed to control the composition of biogas and its physical parameters arising in the process of anaerobic fermentation, with particular purpose for use in places where there is a large number of measuring points (landfills, where large quantities of wells come together in a single collection collector) or for mobile laboratories. The device performs automatic measurement at the push of a button, saves the results of each measurement to the memory and automatically cleans the sensors and measuring path.
