Mercury Monitoring Device

RA-915AM monitors are designed for continuous mercury measurements in ambient air, indoor air and in natural gas. Ideal for permanent unattended installation at air monitoring stations, RA-915AM monitor for ambient air allows ultra-sensitive measurements of background Hg concentrations and is compliant with the European standard EN 15852 for ambient air monitoring.

The monitors feature fully-automated unattended operation without the need for the monthly technician maintenance and frequent recalibration. The use of the instrument allows cutting down operation costs as the analyzer requires no argon cylinders for operation and no consumables.

The remote data transfer makes it possible to connect the monitor to data collection systems via RS232, Modbus, and analogue output.
