Capable of monitoring from one to five gases through diffusion or sample draw, the BM25 packs the benefits of a fixed-system area monitor into an easily transportable, yet rugged instrument.
Designed for team protection or area surveillance, the unit is most suitable for perimeter monitoring, rig overhauls, and mobile or short-term work in areas where fixed detection systems are not suitable.
There are 17 interchangeable “smart” sensor options available for the BM25, making the system easily adaptable to a variety of applications and industries. When the BM25 detects a hazardous level of oxygen, toxic or combustible gas, the top-mounted beacon sends a flashing, bright signal in all directions while emitting a powerful, 103 dB siren alarm.
The BM25 can be used as a stand-alone monitor or wired so that alarm signals transfer from one unit to another. This setup can create a safety perimeter around a detected atmospheric hazard, or transmit a manually initiated emergency signal over a wide area.
The BM25 comes standard with a high capacity nickelmetal-hydride battery pack offering up to 170 hours of continuous runtime. Long-term area monitoring is possible in hazardous locations with an intrinsically safe trickle charge power supply. Also standard are STEL and TWA readings and nearly four months of datalogging capacity for a five-gas configuration.
