The DAX 420-IR detector was designed to continuously measure the presence of various gases in the air.
\nIts operating principle, infrared, gives it its major benefits:
\n– very long lifetime,
\n– increased gas detection selectivity,
\n– immunity to poisons and,
\n– low maintenance cost.
\nBy connecting it to a Dalemans unit or to any other instrument that can receive a 4..20 mA signal, you will benefit from a highly flexible installation.<\/p>\n\n\n\n
