F l e x i b l e . R e l i a b l e . A C CURATE . Biogas Generation GLOBAL DISTRIBUTION NETWORK Biogas is an extremely valuable renewable energy resource and is becoming increasingly more important in reducing our reliance on fossil fuels to produce energy. The main combustible component, like natural gas, is methane (CH4) which can power an engine generator. Monitoring of oxygen levels within the process is required to ensure anaerobic conditions are maintained in the digester and that the methane/oxygen mix does not reach explosive levels. If increasing oxygen levels are detected then it indicates an air leak into the system with the likely risk of a potential explosive hazard. Other gases present include hydrogen sulphide( H2S), a highly toxic and corrosive gas that needs to be monitored to prevent plant damage and health risks.

In 2009 Hitech moved into the new purpose built factory of our parent company MTL where Hitech have their own dedicated instrument assembly line, calibration laboratories and sensor manufacturing areas. This coupled with a brand new pcb flow soldering facility, means that Hitech are almost totally self sufficient in terms of the manufacture of proprietary components used in their range of gas analysers.
