Radius BZ1 Area gas monitor

Starting at $5,282.35

The Radius BZ1 multi gas area monitor simultaneously detects up to 7 gases, including: Cl2, CO, H2, H2S, HCN, NO2, NH3, O2, SO2, VOC (volatile organic compounds) and explosive combustible gases (flammable gases, hydrocarbons , solvents & alcohols).

Featuring the LENS Wireless technology (wireless communication), Industrial scientific Radius BZ1 area gas monitors and Ventis Pro portable gas detectors communicate with each other to alert all peers in a connected group in case of any gas alert. Detailed description

Radius BZ1 area gas monitor

The Radius BZ1 is a next generation area gas monitors. It combines the latest enhanced gas detection technologies (more efficient gas sensors) to outdoor ruggedness (waterproof, multidirectional signal).

The Industrial Scientific Radius BZ1 has been designed with a very modular structure including a high visibility orange base that looks like a signaling cone and a SafeCore™ module which includes gas sensors and any monitor option (sampling pump, communication module...). Thanks to this architecture, only the SafeCore™ module shall be returned for maintenance or periodical checking...

Industrial Scientific Radius BZ1 area monitor assets

Detect up to seven gases using 15 sensor options including PID


  • The most enduring area detector with a typical 7 day run time (168 hours) 
  • External intrinsically safe power supply to extend battery run time up to one month 
  • Ultra-bright red and blue lights and distinctive tones to alert
  • 108 dB at 1 m audible alarm to alert in very noisy environments
  • Market’s largest screen on an area gas monitor
  • Intuitive configuration and textual navigation
  • Customizable action texts in case of alarm such as “EVACUATE” or “VENTILATE”
  • LENS™ wireless network (optional) preconfigured requiring no installation of infrastructure
  • 360-degree gas path and all-weather sensor deployment for more accurate measure
  • The DualSense technology improves safety using two sensors to detect the same gas
