risks
Biogas systems generate gases through the breakdown of organic matter. Monitoring gas levels helps:
Detect methane leaks early
Reduce explosion and fire risks
Improve process efficiency
Support environmental compliance
Continuous monitoring is essential in anaerobic digestion and gas storage environments.
Methane is highly flammable, while hydrogen sulphide is extremely toxic even at low concentrations. Monitoring helps:
Protect workers from exposure
Reduce operational risk
Provide early warning alerts
Support safe confined space entry
Agricultural operations often involve confined spaces such as:
Slurry tanks
Manure pits
Silos
Pump chambers
Grain bins and storage vessels
Digesters
Portable gas detection equipment helps ensure safe entry and maintenance procedures.

Methane is highly flammable and can create explosion risks if leaks are not detected early. It can also cause severe asphyxiation risks when high concentrations displace oxygen in confined spaces.
Agricultural gas detection involves monitoring hazardous gases in farming and agricultural environments to protect workers and equipment.
Hydrogen sulphide is highly toxic and can quickly become dangerous in enclosed agricultural environments such as slurry tanks, especially if manure is mixed or agitated
Common equipment includes:
Portable gas detectors
Fixed gas detection systems
Methane monitoring systems
Confined space gas monitors.
