GasClam Ground Gas Monitor
Product Information
Products
Use the GasClam Ground Gas monitor to meausre CH4, O2, CO2, CO, H2S and VOCs continuously for up to 3 months!
The GasClam is the first ground gas monitor to give continuous, unmanned data collection. Ideal for landfill gas monitoring applications, the GasClam ground gas monitor logs long-term, real trend information. A revolution in gas management and risk prediction, informed decisions can now be made on accurate, reliable data.
The GasClam gas monitor measures methane, carbon dioxide and oxygen concentrations as well as atmospheric pressure and temperature. Optional CO, H2S and VOC, plus water depth are available along with a telemetry module for remote, real time data communication.
The gas monitor’s sampling frequency can be set and is variable from two minutes, to once daily. Data is downloaded to a PC or viewed remotely using the optional GPRS telemetry system.
Manufactured from stainless steel, the GasClam ground gas monitor is Intrinsically Safe, environmentally sealed and ingress protection rated IP-68. Battery operated; GasClam can be powered for up to 1 month based on hourly sampling.
