Radius® BZ1 Area Monitor

Trust the area monitor designed for the world’s harshest environments. Alarms that sound at 108dB, bold LED lights, and clear alarm action messages like “EVACUATE” cut through even the busiest work areas. With local and remote monitoring options, everyone from teams working nearby to safety managers off site will know there’s a hazard and how to respond.

Manufacturer: Industrial Scientific

Radius® BZ1 Area Monitor

Features

  • Never miss an alarm thanks to old, bright LED lights.
  • Show gas readings from nearby monitors so you know what's happening across your site and to your peers.
  • Gain visibility from a distance with a large, easy-to-read screen.
  • Get to work faster with drop-and-go setup and a sturdy all-weather base.
  • Cut right through high-noise environments with alarms that sound at 108 dB, plus bold LED lights.
  • Know what’s happening at a distance with the largest display of any area monitor and customizable alarm action messages, such as "EVACUATE" or "VENTILATE."
  • Minimize the cost of labor and risks of charging and rotating equipment in hazardous locations using Solar Power Supply, which gives you unlimited run time.
  • DualSense® Technology uses two sensors to detect the same gas, bolstering your safety efforts.
  • With Radius BZ1, you can detect up to seven gases simultaneously using 18 sensor options, including photoionization detectors (PID).

Q&A

Area monitors are a highly flexible solution because they can be placed in temporary or long-term configurations based on your specific hazards. With the addition of LENS™ Wireless, networks are created right out of the box and provide visibility into gas hazards in any location. 

Perimeter Monitoring: Set up monitors around a tank, hot work, or other known hazardous area to continuously monitor for gas leaks.
Fence Line Monitoring: Create a barrier between a safe zone and hazardous work area. Use the hopping capability of LENS Wireless to know what is happening up to 1.5 kilometers away.
Confined Space Monitoring: Know what’s happening in a confined space by using the pumped SafeCore Module and tubing to draw air samples to the monitor.

Radius BZ1 can detect up to seven gases at once. Select from 18 sensors including: 

Ammonia (NH3), carbon monoxide (CO), carbon monoxide (CO/H2 low), carbon monoxide/hydrogen sulfide (COSH), chlorine (Cl2), hydrogen (H2), hydrogen sulfide (H2S), hydrogen cyanide (HCN), nitrogen dioxide (NO2), oxygen (O2), sulfur dioxide (SO2), phosphine (PH3), nitric oxide (NO), photoionization detectors (PID),Chlorine Dioxide (ClO2), Hydrogen Chloride (HCl), Hydrocarbon IR (Propane), Methane IR (CH4)

The Radius BZ1 has a typical run time of seven days (168 hours).
The Extended Run Time Power Supply can extend battery to over one month, or the Solar Power Supply can power the Radius Bz1 for an unlimited period.

Loud audible alarms and different colored strobes for gas and non-gas events ensure workers not only know when the monitor is alarming, but why. These alarms cut through high-noise environments with sounds at 108 dB and a display that is three times larger than competitors’ screens. You can also customize alarm action messages to appear on screen during emergencies, such as “EVACUATE” or “VENTILATE.”

Whether setting up a perimeter or monitoring leaks and confined spaces, the Radius BZ1 allows for flexible deployments to create buffers between workers and gas hazards. 

Communicate gas hazards during emergency response, long-term projects, or while performing routine worksite maintenance by adding area monitors wherever they are needed. 
Deploy monitors for temporary work without worrying about battery life. The Radius BZ1 boasts 7 days (168 hours) of typical battery life and the option to extend it to over a month using the external power supply or indefinitely using the Solar Power Supply. 
Accurately detect gases regardless of environmental conditions and avoid false alarms thanks to the 360-degree gas path and all-weather sensor deployment.

Yes, it integrates with other gas monitors through LENS Wireless. With this connectivity, you can create wireless networks out of the box, with no set up or extra equipment required.

Receive alarms and real-time gas readings from any other monitor on the network with long-range communication—up to 300 meters (1,000 feet)—between units. You can also see gas readings and alarms from Ventis® Pro5 personal monitors that have joined the wireless group.

The Radius BZ1 is also compatible with SAFER One Dynamic Plume Modeling Software, so you can identify where a leak is coming from and where it is going.

Yes, you can.

Remote locations rarely offer easy access to electrical power. And if the location is far away, you won’t want to send workers out every few hours or days to charge batteries—that’s a waste of valuable time for all involved.
Using the Radius BZ1 with our Solar Power Supply eliminates three critical area monitoring challenges: runtime, hazard certifications, and portability. Solar panels provide unlimited runtime for up to two Radius BZ1 Area Monitors, RGX Gateways, or a combination of the two, while a CSA Class 1 Div 2 certification ensures safety in even the most hazardous locations. A portable, modular design allows a single worker to transport and assemble the Solar Power Supply.
By addressing these common challenges, you can eliminate the costs and hazards associated with charging and rotating devices in the field.
