AIR MONITOR-GAS, GROSS BETA GAMMA

PARTICULATE AND IODINE

Model # BAM-4HVM

DESCRIPTION: The BAM-4HVM series are four channel air monitors for simultaneous measuring of gross beta/gamma particulates and gaseous radioactivity and Iodine. Like all of the BAM-4 series, these are continuous duty, high capacity, rugged skid or caster-mounted systems. Electronics are microprocessor with color LCD display. Also preamps etc. are plug-in modules allowing change or addition of function as needed and allowing rapid repair by substitution of modules in the field. The modular system is covered by T/A's unique exchange warranty, in addition to the full one year warranty covering all T/A products.   Shields are void free lead encased in welded steel and with stainless steel liners for a long, useful life and easy decontamination. Filters are easily changed via quick disconnect, o-ring sealed filter holder. Shield can be opened for filter change or cleaning with minimum effort. All shield connections and openings are sealed against air leaks. The air moving system is based on a high capacity air pump capable of delivering 5 cfm (Optional up to 30 cfm) free air and including fine regulation in the 3 cfm to 5 cfm operating range. The entire system is mounted in a self-contained rugged cabinet and comes complete with all cabling and connectors in place ready to operate. The standard unit is operated from 115 V single phase, 60 Hz; 220 V optional, 50 or 60 Hz.
