Stationary Gas Monitor
Stationary gas monitor mamos-300 with integrated peltier gas dryer

The maMoS-300/400 is a high quality stationary monitor for continuous measurement of three or four gas components. It is produced using all the newest technological developments. The monitor comes complete with filter, Peltier dryer and condensate pump.
It can be fitted with either infrared or electrochemical sensors or both. The possible sensors are: (electrochemical) O2, CO, NO, NO2, SO2, H2S or: (IR) CO2, N2O, CH4.
The gas monitor is fitted with analogue outputs for current and voltage to allow control functions as well as measurement. There is also a digital data output if needed.

The instrument operates fully automatically in one of two possible cycle forms:

  • continuous
  • Measurement on timetable

Both of these cycle types is freely programmable. Details
