QED Environmental Systems, Inc

- Model BIOGAS 3000 - Fixed Biogas and Landfill Gas Analyser



The new ATEX certified BIOGAS 3000 builds on field-proven, robust gas analysis technology to offer cost effective online monitoring with local data outputs.

Colour screen within robust unit

A 4.3” colour LED-back lit LCD is visible through a window in the IP65 rated stainless steel enclosure, allowing busy technicians to monitor readings on the go in all light and weather conditions. The intuitive user interface makes use of icons and colour to clearly indicate system status, alarms and settings.

Additional gases

Increase the number of gases sampled from 3 to 5, by incorporating external sensors in a choice to 3 gases - CO, H2 and H2S. H2S is available in ranges from 50ppm to 10,000ppm, and can be used in parallel with an internal sensor to measure pre and post desulphurisation. Pre-calibrated sensors, that prevent system downtime, are also available to users as required.

ATEX certified heater

Used to avoid condensation problems, it extends the lowest operating temperature from 0°C to -20°C.

Moisture management

Designed to prevent damage from water ingress and condensation and is fitted as standard. Includes a liquid level indicator with a dedicated alarm notification or the option for an automatic drain which empties the catchpot without manual intervention, offering flexibility for on-site maintenance.

Connect with site systems

Various communication options are available to your SCADA system, including six configurable 4-20mA outputs, customisable relays and Modbus, Profinet or Profibus. Multi-point sampling enables monitoring of up to four different sample points, monitoring before and after desulphurisation or continuous monitoring.

BIOGAS 3000 Module

The system is designed to avoid unnecessary downtime: you can return the module to your local service agent for servicing and receive a temporary replacement unit. All system settings and user preferences are stored separate from the module on the local system, so you won’t even have to re-configure your system.
