CH4 | CO2 | H2S | O2 | H2 The BioBasic is a gas measuring device that is specially designed for the fast and reliable online measurement of biogas, sewage gas and landfill gas. APPLICATION The BioBasic measures the quality of the process gas and thus enables efficient process control. The results are shown on a display and can be transmitted via an interface, allowing you to monitor biogas production and ensure that your plant is running smoothly. Plug & Play Easy operation via touch panel Errors/faults displayed in plain text Flexible data transmission Up to 5 sample gas inputs High long-term stability due to NDIR measurement method developed in-house • High economic efficiency with low service costs AREAS OF APPLICATION • Biogas plants • Sewage treatment plants • Landfills • Power-to-gas Fresenius Umwelttechnik GmbH Doncaster-Platz 5 [email protected] www.fresenius-ut.com

Technical Data Measurement Technology IR: NDIR dual-pressure reference method, cuvette heated to 60°C EC: electrochemical measurement method Measurement Range Measurement Uncertainty = 3 % of the measured value Long-term drift < 3 % / anno (IR) Detection Limit Measurement Interval per measuring point (CH4, CO2, O2): interval adjustable 15 - 999 min + 180 s pre-purge + 20 s measurement (dual-pressure cycle) + 240 s post-purge = approx. 22 min 20 s per measuring point H2S: Standard: 3x / day, depending on sample gas concentration and installed sensor (2,000 ppm / 10,000 ppm) Measured Value Correction...
