  • Deploy whenever and wherever - whether setting up a perimeter, or monitoring leaks or confined spaces, the Radius BZ1 allows for flexible deployments to create buffers between workers and gas hazards
  • Detect up to seven gases using 15 sensor options including PID
  • Longest running area monitor with a typical run time of 7 days (168 hours)
  • Audible alarms sound at 108 dB at 1 m to cut through high-noise environments and different colored strobes activate for gas and non-gas events to ensure workers not only know when the instrument is alarming, but why
  • LENS™ Wireless enables communication between area monitors and Ventis™ Pro Series personal monitors so you can know what is happening without approaching
  • Largest display of any area monitor on the market
  • React with confidence and identify gases and alarms from a safe distance, and read critical safety messages such as "EVACUATE" or "VENTILATE," thanks to a display that is three times larger than its nearest competitors'
  • DualSense® Technology increases worker safety by using two sensors to detect the same gas
  • iNet ® and DSX™ Docking Station ready

LENS™ Wireless is the first gas detection solution that allows personal monitors and area monitors to share gas readings and alarms with one another. Now when a gas hazard, man-down, or panic situation causes an instrument to alarm, all peers in the connected group will instantly be notified of the hazard and the person in danger. When seconds matter, you can rely on help from workers nearby, rather a control room or call center hundreds of miles away.

  • Share gas readings and alarms between Ventis™ Pro Series personal monitors and Radius™ BZ1 Area Monitors
  • Enjoy out-of-the-box operation with no site surveys, IT setup, licenses, or additional infrastructure needed
  • Identify peer alarm types in real time, enabling a faster, more appropriate response
  • View gas readings from other peers in your group on any monitor without needing a central controller to relay the information
  • Receive readings from up to 1.5 km (~1 mile) away with wireless hopping between instruments
  • Activate the panic alarm on your personal monitor to notify all peers in your group of an emergency
  • Depend on self-healing mesh networks to always stay connected, even if a single unit drops off


  • WARRANTY: Two-year warranty, including sensors and battery
  • DIMENSIONS: 29 x 29 x 55 cm (11.5 x 11.5 x 21.5 in)
  • WEIGHT: 7.5 kg (16.5 lb)
  • OPERATING TEMPERATURE RANGE: -20°C to 55°C (-4°F to 131°F)
