BW Ultra Confined Space Multi-Gas Detector

Designed specifically for sampling and monitoring confined spaces, the Honeywell BW Ultra is a multi-gas detector with the ability to monitor up to five gases simultaneously. The robust sample draw pump can pull a sample from up to 75 ft, and the 1-Series sensors offer fast response, reliable performance, and long life, even in extreme environments.


  • Large, easy-to-view screen
  • Enhanced situational awareness for the hole watch
  • The new 1-Series sensor for enhanced reliability
  • Honeywell TouchConnect™ Technology for quick instrument management
  • Remote monitoring for an additional layer of protection.
  • Expected sensor lifetime for sensors of up to five years
