(without compromising lifetime)

Designed as a sensing platform for industrial gas detection systems and other CO detection applications where an explosion proof field device is required, The NET-2X-CO is a completely sealed unit, designed to be replaceable in the field complete. The integral sensor is not field replaceable.

The enclosure is fitted with an external thread at the front end to allow easy fitting of accessories. A choice of two standard rear mounting threads is available. 

THE NET-2X-CO IS ATEX APPROVED
CESI 01 ATEX 066 U
