HI Natalia and great question on why O2 measurement is important in Biogas/RNG industry. There are 2 critical O2 measurement challenges that the Barben OXYvisor solves. First challenge; methanogenic bacteria that is used in the digestor can’t survive in the presence of O2, therefore monitoring the levels is crucial since any increase in O2 can be detrimental in the digester structure. Second challenge; is low explosive limits (LEL) of O2 measurement to provide safety checks in order to avoid exceeding these O2 levels limits. The Barben OXYvisor Optical analyzer, which uses Optical Quench Luminescent, is great for measuring O2 and solves these 2 challenges due to no interference due to moisture, H2S, CO2, & other contaminant gases. Hope this helps and please feel free to ask any more questions!
