The Nemoto NET-2X-30S Pellistor Gas sensor head is a stainless steel enclosure designed to accommodate the Nemoto NP-30S single header pellistor for use as a complete field device operating as a part of a fixed gas detection system.

The heads comprises a stainless steel flameproof enclosure constructed with an integral stainless steel sinter filter for the safe entry of the atmosphere being detected. The single header pellistor series is held in the optimum position for measurement.

Sensor is integral and 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 offered (x = see thread code)

THE NET2X-30S IS ATEX APPROVED
