New diaphragm pumps for stationary gas analysis



New sample gas pumps from KNF for stationary gas analysis systems in process and emission measurement

Sample pumps are selected according to the characteristics of the process gas, the process location and the ambient conditions. Accordingly, manufacturers and operators of instrumentation equipment face a significant challenge in deciding on the optimal feed pump.


In addition to permanently precise measurement results, the three new pump types from KNF offer an even wider range of applications in continuous gas analysis:
