Natural Gas Industrial RA-915AMNG Mercury Analyser
RA-915AMNG monitors are designed for continuous mercury measurements in a natural gas stream and are ideal for permanent unattended installation at the gas monitoring stations.
RA-915AMNG monitor for natural gas allows direct rapid analysis of mercury in natural gas, enables prompt reaction to variations of mercury concentrations in the stream, monitoring of the MRU units and other applications.
The RA-915AMNG monitor requires very little maintenance and attention from the plant personnel (service may be done during maintenance shutdown) and requires no reagents/consumables for operation (only filters and lamp require periodic replacement during planned maintenance).
The remote data transfer makes it possible to connect the monitor to data collection systems via RS232, Modbus, and analogue output.
Features and Benefits
