Radius BZ1

General Information

The Radius® BZ1 Area Monitor is a rugged gas detector that connects your entire worksite. Designed to go where the work is, Radius can be deployed in seconds for emergency response scenarios or left in the field for up to 7 days on a single charge or for an unlimited period with the Solar Power Supply. Radius shares readings and alarms with other units and personal gas monitors through LENS® Wireless allowing you to create a dynamic safety network that changes with the needs of your operations.


  • Detect up to seven gases simultaneously using 18 sensor options including PID
  • Reduce battery swapping with a typical run time of 7 days (168 hours)
  • Cut through high-noise environments with alarms that sound at 108 dB
  • Know what’s happening at a distance thanks to the largest display of any area monitor and customizable alarm action messages such as "EVACUATE" or "VENTILATE"
  • Increase worker safety with DualSense® Technology, which provides redundant protection by using two sensors to detect the same gas
  • Gain real-time visibility and respond faster in an emergency by pairing with the RGX® Gateway for live monitoring
  • Simplify maintenance and reporting with the DSXi Docking Station

Product Description

Area monitors need two things to be efficient: precise sensor technology to detect hazardous gases and the robustness to withstand long outdoor deployments. With the Radius BZ1, all critical technology pieces such as sensors, software, pumps, and wireless are part of the parenred SafeCoreTM module. Smart sensors are positioned face down to prevent the elements from interfering with gas readings resulting in fewer false alarms.The module slides out from the Radius BZ1 base for easy docking and automated maintenance ensuring that your sensors are always ready to provide accurate gas detection. The radius BZ1 base is made of durable, weather-resistant plastic. The base has built-in audio and visual alarms that grab workers attention, even in high noise enviroments. A large battery keeps the unit working as long as you do, and side-grip handels help make the base easy to move from location to location. The Radius BZ1 is available with optional lens wireless. with the LENS Wireless technology, your devices will connect once being turned on- with no need for setup or additional infastructure. You will recieve real time gas readings from other connected instruments on the network, helping your team react faster in emergency situations.

How to Calibrate the Radius BZ1

  1. For diffusion units, slide the prepared calibration cup into the gaspath. Press firmly; verify that thecalibration cup edge is flush with thesurface of the SafeCore Module.For aspirated units, connect the calibration tubing to the pump inlet.
  2. Optionally skip the sensor.Apply calibration gas of the type andconcentration stated on theinstrument's display screen andindicated by the symbol ◄.Aspirated units can draw the gas asneeded from a demand flowr egulator.
  3. To start the flow of gas, turn theregulator's knob in a counterclockwisedirection.Continue to follow the display-screenprompts to apply the requestedcalibration gas. At each prompt, if thegas is not sensed, the instrument willwait up to five minutes to accommodatea change of gas cylinders.
  4. If needed repeat for any failed sensor.
  5. Remove the calibration cup from thegas path: slide it away from theinstrument and set aside or store forfuture use. For aspirated units, simply disconnectthe tubing from the pump inlet.
  6. Stop the flow of gas: turn the regulator knob in a clockwise direction and tighten
