BM 25
MX 40
The BM25 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 BM25 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 MX 40 controller was designed to centralize 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.

The OLCT 10N is a digital combustible gas detector designed for to detect combustible, toxic gases or oxygen.
Designed for the detection of explosive gases, toxic gases or oxygen, this gas detector comes with a Wheatstone bridge output (OLC 100) or 4-20mA output (OLCT 100).
The CTX 300 detector is designed to detect oxygen, toxic and refrigerant gases, and also uses a new sensor for CO2 detection over three different ranges: 0-5000 ppm, 0-5% vol. and 0-100% vol.
