BM 25 WirelessOldham, an IST Company, is pleased to announce that its versatile BM 25 multi-gas monitoring system is now available in a wireless version, offering greater flexibility for a wider range of applications.

The BM 25 detects up to 5 gases simultaneously and can include up to 30 devices in a standard network.  Using a MESH network topology, the BM 25 Wireless connects peer-to-peer allowing each device in a network to receive, send, and relay data. Should a device fail or an obstruction occur, communication automatically re-routes allowing the network to remain in operation, or routes around line-of-sight obstacles, forming multiple networks when necessary. When the obstruction is removed communication quickly reverts back to one network.

Powered by a NiMH battery pack, the BM 25 Wireless offers up to 135 hours of continuous run time and is compatible with Detcon’s Model X-40 controller. Standard features include STEL and TWA values and a datalogging capacity of up-to four months. An intrinsically safe trickle charger is also available for long-term area monitoring in classified zones.

The robust BM 25 Wireless is fast and easy to deploy, provides versatility in coverage, and is highly fault tolerant.  Approvals include ATEX, IECEx; CSA is pending.

Industrial Safety Technologies (IST) is committed to providing innovative safety solutions through its team of dedicated and experienced flame and gas detection companies. Together, Oldham, Detcon, Simtronics, and Gas Measurement Instruments (GMI) manufacture the most comprehensive wireless, portable, and fixed gas and flame detection safety solutions in the world.
