Transportable Multi Gas Monitor BM 25

The BM 25 packs the benefits of a fixed system area monitor into a rugged, user-friendly and transportable instrument. It was designed to detect one to five gases for mobile or temporary work applications, team protection, area surveillance or places where fixed detection systems are not suitable.

Powered by a NiMH battery pack, the BM 25 Multi Gas Monitor offers up to 170 hours of continuous run time. Other standard features include STEL and TWA values, as well as a data-logging capacity of more than four months. Multiple units can be grouped using optional alarm transfer kits. This protects larger areas by transferring alarms from one BM 25 to the next. An intrinsically safe trickle charger is also available for long-term area monitoring in classified zones.

The BM 25 is durable and versatile. It is suitable for a wide range of industries, including refineries and pharmaceutical production. Applications include turnaround work sites, rig overhauls and fence-line surveillance.

The BM 25 Wireless brings you freedom and flexibility while keeping the standard characteristics of the BM 25.

The MX 40 controller was designed to centralise the information transmitted by the BM 25 over a wireless network and can display up to 32 measurements in real-time. When a BM 25 signals an alarm, the MX 40 also goes into alarm mode and can, for example, control internal relays and order other monitors to transmit the alarm as well.
