Sample gas probe GAS 222.31 Amex

In many applications gas analysis is the key to safe and efficient control of process flows, environmental protection, and quality assurance. In the extractive gas analysis, the location of the gas sampling point is crucial for the reproducibility and accuracy of the analysis results. The specific filter capacity, corrosion resistance, and functional equipment requirements for the probe arise from the composition of the sample gas. However, operating costs are also an important criterion in the selection, as the sampling points are frequently located at hard to access points in the system. Effective particle filter backwashing options and low maintenance characterize the extensive GAS probe series.
