Oldham's BM 25 to Remain in Its Product Portfolio

Transportable, Multi-Gas Area Monitor with Five Simultaneous Plug & Play Sensors

Arras, France – Oldham is pleased to confirm that the popular multi-gas area monitor, the BM 25, remains in its product range after the sale of Oldham to Industrial Safety Technologies (IST) on October 31, 2013. The BM 25 was originally designed by Oldham, has always been manufactured Oldham since its original launch, and will continue in the Oldham business under IST ownership. 

Powered by a NiMH battery pack, the BM 25 offers up to 170 hours of continuous run time. Other standard features include STEL and TWA values, as well as a datalogging 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 a rugged, durable mobile monitoring system with global  certifications, long run times, flexible signal options, and a wide array of applications.  The device detects one to five gases for mobile or temporary work applications, team protection, area surveillance or places where fixed detection systems are not suitable.

The BM 25 has been sold in more than 60 countries and with ATEX and CSA certifications, will continue to be available globally from Oldham. Contact your local Oldham sales representative, or visit our website at for more information on the BM 25.
