    Once in a while it is necessary to recalibrate the analyzer. The exact interval time depends on the biogas condition (gas concentration, total measuring time) and shall be determined by the user. MRU recommends at least half yearly calibration. Calibration is carried out by connecting certified gas cylinder to the analyzer. As those cylinders, typically are under high pressure (150 to 200 bar) and they contain toxic and/or flammable gases, make sure that only qualified personal is involved in this calibration procedure.
