BW Gas Alert Micro Clip X3 Gas Detector by Honeywell, can detect Flammable, Oxygen, Carbon Monoxide and Hydrogen Sulphide. With three, two or single gas models available. Life expectancy is five years, with the new BW Technologies O2 sensor not needing replacement, reducing maintenance and overall cost of ownership. IP68 ingress protection allows deployment in extreme environments, protecting against dust and water. The detector can be submerged for 45 minutes at a depth of 1.2 metres.

The GasAlert MicroClip X3 Gas Detector is easy to use, operated by a single button, aided with icons.  Real-time gas concentrations are displayed on the LCD; combustible gas can be viewed in LEL or % volume.  An IntelliFlash gives visual compliance producing a green flashing light; the frequency can be operator adjusted. An audible beep can be initiated when in use. Settings can be programmed to force user calibration or bump test. Auto zeroing can be set to run on startup, along with custom message displayed.

  • Alarms: Visual, vibrating, audible (95 dB)- Low, High, STEL, TWA, OL (over limit)
  • Operational time at least twelve hours constantly down to-20°C
  • Continuous health check of sensors, battery status, circuit integrity. Audible & visual alarms on startup
  • Per ACGIH 1 ppm H2S TWA recommendations
  • Size 11.3 x 6.0 x 3.1 cm, weight 190g
  • Languages supported: English, French, German, Spanish and Portuguese

Honeywell BW Connect BLE Adapter and Field Communicator Device

Field Communicator (FC) is an Android-based mobile application and phone that enables real-time communication
between a worker’s instruments and a remote monitoring system. The phone and the application act as a
personal communication hub for a worker, which collects instrument readings and alarms from instruments over
Bluetooth (BLE) or Wi-Fi and transmits in real-time to a remote system over a 3G/4G/LTE communication network.
The application also transmits a worker’s information and location to the remote system, which allows safety
managers to quickly react and provide necessary assistance in case of an emergency. This solution not only provides
real-time visibility of worker safety, but it also improves productivity with real-time access to remote information and
collaboration with peers.
Note 1: Please note that the Safety Communicator app is NOT pre-loaded onto the Field Communicator
Note 2: A ProRAE Guardian license is needed to connect to Systems’ Real-Time Monitoring
