Air Monitors: MSA FiveStar Alarm Gas Detector
Deluxe, Industrial and Economy Models

The FiveStar Alarm can automatically compensate for changes in atmospheric pressure, and has a battery gas gauge which indicates, in tenths of hours, how much longer the instrument can run on the remaining battery charge. For added protection, MSA's Lockalarm™ Circuit ensures that the unit will remain in alarm mode whenever combustible gas levels reach 100 percent of the LEL (Lower Explosive Limit).

Small and lightweight, the FiveStar Alarm is convenient to carry in hand or clip to a belt. It can also be left unattended for continuous monitoring.

Approvals & Standards: The FiveStar Alarm has been approved for use in Class 1 Division 1, Groups A, B, C and D; Class II, Division 1, Groups E, F, G; and Class III hazardous locations.

Applications: Agriculture, Chemical, Construction, Electric Utility, Fire Fighting, Hazardous Materials, Mining, Nuclear, Oil and Gas, Paper & Pulp, Welding

Hazards: Combustible Atmosphere, Confined Space, Fire, Oxygen Deficiency

Allows the user to select the best combination of sensors to match the requirements at hand. There are eleven sensors to choose from, and as many as five can be used at one time. The sensors can easily be changed and calibrated.
