Trusted Reliability to Keep Teams Safe
- Detect up to seven gases simultaneously (including PID)
- Get more accurate detection with all-weather sensor options and the ability to detect gases across a 360-degree path
- Reliably alert workers to all hazards with:
- Bold LED lights
- Alarms that sound at 105dB, cutting right through any high-noise environment
- Large, easy-to-read display
*Devices relying on a wireless connection feature a runtime up to 30 days; devices without a wireless connection feature a runtime up to 50 days. Additional configurations may affect runtime depending on your site and application.
Make Quicker Decisions
- Customizable alarm messages such as โEVACUATEโ or โVENTILATEโ
- Seamlessly share alarms between personal and area monitors across an entire site with our LENSโข Wireless technology
- Ensure accurate readings and reduces false alarms by relying on two sensors to detect the same gas with DualSenseยฎ technology
Maximize Team Safety (LENS Wireless)
LENS Wireless is a local team-based peer-to-peer (P2P) communications that gives your team improved hazard awareness that leads to faster emergency responses. Devices connect within seconds after being turned on โ with no need for IT setup, configuration, or additional infrastructure. Simply link devices to form a connected group of monitors to create a dynamic safety net across your worksite. Devices will communicate between one another even in the harshest environments.
SafeCore Sensor:
Each piece of critical technology for the Radius BZ1, such as sensors, software, pumps, and wireless configurations, live inside the SafeCoreยฎ module. This smart sensor is positioned face down to prevent the elements from interfering with
gas readings, resulting in fewer false alarms โ even in the harshest environments. The module also slides out from the Radius base for easy docking and automated maintenance, ensuring that your sensors are always ready to go. Plus, you can even swap
sensors out in the field, so the Radius base never has to leave its spot.
DSX Docking Station:
Manual maintenance and record keeping are time-consuming and prone to error. The DSX Docking Station is a cloud- connected solution that gives you complete control to schedule maintenance and firmware updates โ so your area monitors are always ready when you need them. Plus, the DSX Docking Station can automatically perform any calibrations needed for your SafeCore sensor.
RGX Gateway:
The portable RGXโข Gateway transmits location, gas readings, and real-time alerts from anywhere, including hazardous locations, giving you the power to respond faster and to improve site productivity. By using the Radius BZ1 and the RGX Gateway, you can ensure your information is always backed up and available on the cloud โ making it easier to access wherever you are.
