The BIOGAS3000 is a fixed biogas and landfill gas analyser designed for continuous gas monitoring in anaerobic digestion and landfill applications.

Robust, modular analyser for continuous biogas monitoring with zero operational downtime.

Features

Standard measurements for CH₄, CO₂ & O₂
Optional measurements: H₂S, H₂, CO (up to two additional gases)
Modular design allowing easy maintenance and hot-swap modules
User calibration to ensure accuracy in extreme temperatures
ATEX and IECEx certified for use in potentially explosive atmospheres (zone 2)
ISO / IEC 17025 calibration for optimal accuracy
Continuous monitoring with up to 4 configurable sample points
IP65 rated weatherproof stainless steel enclosure
Alarms for gas levels, faults and liquid level monitoring
6 x 4-20mA analogue outputs, Modbus RTU communication, optional Profibus/Profinet
Ultra-clear, informative full colour display
Operating temperature: 0°C to +50°C without heater, -20°C to +50°C with heater
Extended warranty & service pack options

Sectors & Applications

Biogas and landfill gas operations
Agricultural waste management
Biogas upgrading and flaring
Food & farm waste AD, sewage/wastewater treatment AD

Benefits

Customisable configuration to site requirements
Zero downtime due to modular, hot-swap servicing
Reliability and longevity; protected from damaging gases
Operational in hazardous/explosive environments
Minimises through-life costs, easy to operate and install
Multi-lingual interface
