Oldham BM 25 Multi Gas Detector
The Oldham BM 25 is a rugged, user-friendly, transportable Multi Gas Detector.
The Oldham BM 25 is a rugged, user-friendly, transportable Multi Gas Detector. The Oldham BM25 is designed to detect up to five gases for mobile or temporary work applications, team protection, area surveillance or places where fixed detection systems are not suitable.
The Oldham BM25 Gas Detector is powered by a NiMH battery pack which offers up to 170 hours of run time. Multiple units can be grouped by using optional alarm transfer kits. This protects larger areas by transferring alarms from 1 device to the next.
