QED Environmental Systems Announces LANDTEC BIOGAS 3000 Fixed Gas Analyzer

Offering optimal continuous monitoring of gas production process

DEXTER, MI - QED Environmental Systems, Inc., a leading manufacturer of innovative environmental products and subsidiary of Graco Inc. (NYSE: GGG), announces the new LANDTEC® BIOGAS 3000™ fixed gas analyzer, a next-generation system offering continuous monitoring of the complete gas production process. Building on field-proven gas analysis technology, the compact, self-contained BIOGAS 3000 system offers cost-effective online monitoring that is ideal for anaerobic digestion, biogas monitoring and landfill gas monitoring applications.


The new BIOGAS 3000 fixed gas analyzer can utilize up to four sample ports to monitor methane (CH4), carbon dioxide (CO2) and oxygen (O2), with optional monitoring of hydrogen sulfide (H2S), hydrogen (H2) and carbon monoxide (CO) levels. Operators can choose up to five gases to monitor. The device features easy self-installation and maintenance, and QED provides a temporary replacement unit during service, resulting in zero operational downtime for servicing. The BIOGAS 3000 system offers simple user calibration and an easy-to-operate system. The system is calibrated to ISO/IEC 17025 standards for optimum accuracy.

The BIOGAS 3000 fixed gas analyzer is available with a continuous monitoring option for CH4, CO2 and O2, and by incorporating external H2S sensors in ranges from 50ppm to 10,000ppm, it can be used to monitor before and after desulphurization. In addition, pre-calibrated sensors that prevent system downtime are available to users as required. A built-in liquid level monitoring with dedicated alarm and moisture removal drain or the option for an automatic drain which empties the catchpot without manual intervention, offers flexibility for on-site maintenance.

Built with an IP65-rated enclosure, the BIOGAS 3000 system is certified for use in potentially explosive atmospheres (ATEX) and IECEx (IEC System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres) Zone 2 areas. Various communication options are available to your SCADA system, including six configurable 4-20mA outputs with a Modbus RTU communication protocol. In addition, process Field Bus (PROFIBUS) and Process Field Net (PROFINET) and Ethernet communication protocols are also offered.
