This explains why the sample gas probe is the important interface between the process and the analyser system.

Quality, reliability and low operation cost have been the main targets for the development of this programme. The results are outstanding: the modular design allows application specific combinations in a very price effective manner.

The GAS 222 series of sample probes provides "down to earth" solutions based on advanced modular designs.Depending on the application, a variaty of heated or unheated basis units can be combined with in-situ or downstream filters. The filter material can be chosen from sintered ceramic to sintered stainless steel or even pleated stainless steel. Filters with large surfaces provide long life time. For the in-situ filters a highly efficient blowback system is available at reasonable cost.

The ECO series covers a broad range of applications with high dust loads but do not require heating. The directly attached blowback devices plus a variaty of filter elements with large surface areas are the features of these probes.

The APO series provides professional material for simple
