The ADR02 is a versatile pressure governor that can be customized to your requirements. The scope of application extends from an unheated device with no housing (e.g. for EGR measurements) to a continuously heated, fully enclosed module for e.g. pre-cat measurements with particle load.

The ADR02 can optionally be supplied as an NO pressure governor, reducing inlet pressures of up to 6bar to an outlet pressure of max. 250mBar; or as an NC pressure governor that remains closed to max. 3bar inlet pressure until a vacuum of -70mBar relative pressure is applied on the sample gas outlet (e.g. when the measuring device begins to pull). During measurement the vacuum controller adjusts inlet pressures of up to 6bar to max. 50mBar on the outlet. The conversion process from overpressure to vacuum controller and back can be carried out by the user in just a few minutes.

External heating control can be carried out using any current temperature regulator. All IAG devices can be fitted with pin assignment, gas connectors and temperature sensor type according to customer requirements. And finally, fast availability and attractive prices for replacement parts make a valuable contribution to the quality and efficiency of your test cell operation.
