Description

The SWG100 BIOcompact is a cost effective fixed biogas Analyser ideal for use on reduced scale Anaerobic Digestion plants, from agricultural to food waste applications.  This super compact fixed gas analyser is a valid and cost effective solution to a portable gas analyser.

The SWG100 BIOcompact biogas analyser can be configured to measure Oxygen (02%), Methane ( CH4%), Carbon Dioxide(CO2%) and Hydrogen Sulphide (H2S) from a single or dual sampling points.

The system automatically measure up to 24 times a day (with user defined intervals) or on demand by simply pressing a button. This features allow the operator to take additional gas readings as required outside the timed measurement sampling programme.

The Biogas readings are automatically stored to the internal SD card for easy transfer to a PC for future analysis. No special software is required as data are saved in CSV format.

The system offers standard RS 485 and Modbus communications, and optional 4 x 4-20 mA analogue output, profibus and ethernet industrial interfaces.

The SWG100 BIOcompact is easy to operate, self install and with the lower cost of ownership.
