Product of the week - Radius BZ1 Area Monitor

Worry less with the Radius BZ1 Area Monitor, the ultimate solution to gas detection.

The Radius BZ1 Area Monitor accurately detects gases regardless of environmental conditions without the hassle of intricate wireless setups and maintenance routines. Focus on the job in hand whilst the Radius BZ1 effortlessly protects you and your personnel from gas hazards with its real-time gas readings and loud audible alarms.

The rugged Radius BZ1 provides an industry-leading run time of 7 days (168 continuous hours) whilst exceeding at gas detection, connectivity, and ease of use. Should a gas hazard occur, the Radius BZ1 springs into action immediately, ensuring personnel remain safe owing to its distinctive audio and visual cues. Its audible alarms sound at 108dB at 1m to cut through high-noise environments and the alarm action message is customisable, such as "EVACUATE" or "VENTILATE". Personnel can easily differentiate between critical and non-critical events based on ultra-bright blue and red lights on the Radius BZ1, and it has the largest display of any area monitor on the market.

Share gas readings and alarms between monitors and increase safety with the LENS wireless peer-to-peer communication system. With the LENS wireless system, users can receive alarms and real-time gas readings from any other instrument on the network and get long-range communication – up to 300m between units – with minimal impact on the instrument’s best-in-class run time. It works out of the box, forming a network automatically without the need for a central controller, IT setup, or infrastructure. Owing to the simplicity of the LENS wireless system, personnel can respond faster when gas emergencies occur.

The design of the Radius BZ1 means less time managing the instrument, and more time spent on the project. The area monitor is easy to maintain thanks to a unique modular design, the DSX docking station and patented DualSense technology. Automatically bump, calibrate, manage settings, and update software for the removable SafeCore modules using the DSX docking stations, and the DualSense technology uses redundant sensors to determine the concentration of the target gas in the atmosphere, reducing the risk of instrument failure.

The Radius BZ1 is used outdoors and indoors for applications that require a worker or worksite perimeter, a fence-line setup, a standalone unit, and confined-space monitoring. Hire the intrinsically safe Radius BZ1 Area Monitor today and ensure complete safety on site for all personnel.
