Honeywell E3Point Nitrogen Dioxide NO2 Remote Sensor E3SRMNO2

Notify me when this product is available:

This E3 Point Remote Sensor is a toxic or combustible gas detection sensor that is compatible with the E3 Point Standalone sensor or with the features offered in certain controller type products. It provides continuous monitoring for Nitrogen Dioxide in ambient air. The E3 Point is designed to be mounted on an extra wide (2 3/8") electrical box. The E3 Point Remote Sensor is intended for use exclusively with the E3 Point Standalone unit. No other uses are supported by Honeywell Analytics.

  • Uses: Wall or duct-mounted gas detector for monitoring carbon monoxide (CO), nitrogen dioxide (NO2), oxygen (O2), methane (CH4), hydrogen (H2), hydrogen sulphide (H2S), and propane (C3H8), installed as a standalone device with single-gas or dual-gas monitoring. (Note: E3Point standalone version replaces Vulcain models VA201T, VA201M and VA301M)
