DAX 3F-IR

The DAX 3F-I detector was designed to continuously measure the presence of various explosive gases in the air.
Its measurement principle, catalytic combustion, gives it its major benefits:
- very short response time,
- accuracy and reliability of measurements.
By connecting it to a Dalemans unit, you will obtain a very high performance installation.
ATEX certified and with a stainless steel casing, this detector is especially suitable for applications in aggressive environments or environments where hygiene is essential.
