The DAX 420 detector was designed to continuously measure the presence of various explosive gases in the air.
\nIts measurement principle, catalytic combustion, gives it its major benefits:
\n– very short response time,
\n– accuracy and reliability of measurements.
\nBy connecting it to a Dalemans unit or to any other instrument that can receive a 4..20 mA
\nsignal, you will benefit from a highly flexible installation.
\nATEX certified, this detector is especially suitable for the industrial sector, whose applications are located in an explosive atmosphere.<\/p>\n\n\n\n
