The DTX 420 detector was designed to continuously measure the presence of various toxic gases in the air such as carbon monoxide and ammonia but also oxygen.
\nIts electrochemical measurement principle gives it its major assets:
\n– measurement stability,
\n– selectivity of the gas to be detected and high accuracy.
\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.
\nThis detector is especially suitable for applications like underground car parks, laboratories and cooling systems.<\/p>\n\n\n\n
