1) Landtec GEM 2000 Plus Infrared and catalytic gas sensors: Measures methane, oxygen, carbon dioxide, hydrogen sulphide, carbon monoxide, and
static pressure. Sensitivity range 0-100% methane, 0-25% oxygen, 0-100% carbon dioxide, 0-200 ppm hydrogen sulphide, and 0-2000 ppm carbon
monoxide. Calibrated to methane, oxygen and carbon dioxide. Measured directly from Well.
2) Mini RAE 2000: OVM (Organic Vapour Monitor) equiped with a photoionization detector. Sensitivity range 1 to 10,000 ppm. The Mini RAE does
not measure methane. Measurements were taken from a tedlar bag.
