MF420-P

The measuring systems of the product family MF420-P, with a catalytic sensor (pellistor), determine the concentration of explosive gases and vapors in air mixtures. The concentration is given out via a 4 - 20 mA interface for further processing. The sensor is characterized by its high measurement accuracy and by its long life cycle. The measuring range is from 0 – 100% LEL.

In combination with our limit monitors (GWZ) gas measurement systems for detection of explosive gases and vapors in ambient air, like eg. storage facilities, can be set up.

Measuring Ranges

The measuring ranges depend on the measured gas or vapor. For a table of ranges please refer to the product assortment. Other gases, vapors, and concentrations are also possible on request.

Certifications

The device complies with the generic standard EN 50270:2015 Type 1 and Tyee 2 and Directive 2014/30/EC.

Maintenance and Service

The device is delivered already calibrated. The maintenance cycle must / should correspond to the given safety requirements. We recommend at least a semi-annual inspection of the equipment by qualified personnel. You can also use our service.

For more details, please refer to the technical data or ask our contact person.
