Radius BZ1 Area Gas Monitor

Rely on Radius BZ1 Area Gas Monitor to protect your worksite from hazardous gases. Protects workers longer with less setup, training, and time in the shop.

Radius BZ1 is the successor to Industrial Scientific’s BM25 area gas monitor.

Radius BZ1 at a glance…

  • Detect up to 7 gases using 15 sensor options, including PID.
  • Extra-long-running area gas monitor with a typical run time of 7 days (168 hours).
  • Audible alarms sound at 108 dB at 1 metre to cut through high-noise environments.
  • LENS™ Wireless networks share alarms and data with no setup or infrastructure required.
  • Extra-large display… larger than any area gas monitor we have ever sold.
  • Customisable alarm action messages such as “EVACUATE” or “VENTILATE”.
  • DualSense® Technology increases worker safety by using two sensors to detect the same gas.
  • iNet® and DSX™ Docking Station ready.


      Radius BZ1 Area Gas Monitor just works, no questions asked. This frees your teams to focus on what’s important and be confident that their area gas monitors are ready for anything that comes their way.

      • Really easy: Whether setting up a perimeter, or monitoring leaks or confined spaces, deploy Radius BZ1 area gas monitors whenever and wherever required to create buffers between workers and gas hazards.
      • Loud and clear: Loud audible alarms and different coloured strobes for gas and non-gas events ensure workers know when the gas monitor is alarming, and why it’s alarming.
      • React with confidence: Identify gases and alarms from a safe distance and read critical safety messages such as “EVACUATE” or “VENTILATE,” thanks to a display that is 3x larger than the closest comparable area gas monitor.
      • Know what’s happening at distance: Create wireless networks out of the box and receive real-time gas readings from other gas monitors thanks to LENS Wireless and its automatic, peer-to-peer mesh network.
      • Spend less time managing your monitors: Your gas monitor will spend more time in the field and less time in the shop thanks to a unique modular design, the DSX™ Docking Station, and patented DualSense ® Technology.
