The IMR 550P device is for the cleaning of gases and is suitable for use in conjunction with all gas measuring and analysis instruments. It is encased in a handy portable case. It is especially designed for use with the IMR 1400 and IMR 2800 series or any other type of combustion gas analyzer. The gas is filtered by the 3 micron filter and then heated by the sampling hose. The unique microprocessor controlled Peltier Cooler of the IMR 550P has been designed with a powerful dew point stabilizer. The dew point is set to 4°C. The condensate that is formed is removed by a peristaltic pump.
