  • If we would have worked with fire watch attendants versus the Radius BZ1 area monitors for this project, it would have cost the customer at least double and required more work permits. What immediately drove us to choose the Radius BZ1 was the battery life. We knew that we would be able to let every monitor run for seven or eight days, instead of having to send out 10 people per shift per day to change out batteries, like another manufacturer’s instruments that we used in the past. With Radius BZ1, we never missed a beat!

Radius BZ1 Frequently Asked Questions

How can I use an Area Monitor?

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.

What sensors does Radius BZ1 support?

Radius BZ1 can detect up to seven gases at once. Select from 22 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), infrared (IR), and more

What is the Radius BZ1’s runtime?

The Radius BZ1 features a runtime of up to 50 days, depending on configuration, or for an unlimited period based on different external power supply options.

How will I be alerted if a gas hazard is present?

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 105 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.”

How do you deploy the monitor?

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 up to 50 days of battery life, depending on configuration, and the option to extend runtime of certain configurations 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.
Does the Radius BZ1 communicate with other devices?

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.

Can you use an area monitor in a remote or hazardous location?

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.
