Unmanned continuous atmospheric and gas-borne mercury monitor
The model AM-4 is intended for collecting mercury present in gas as a gold amalgam and then continuously measuring it on an unmanned basis. This model has the ultrahigh sensitivity of 0.2 pg as the lower detection limit, enabling short-term measurements repeatedly. It is also capable of automatically making standard calibrations at preset time intervals (optional). And along with that, this model can be housed in a JIS- or EIA-compliant 19-inch rack.
