AIR MONITOR-GAS, GROSS BETA-GAMMA
& ALPHA PARTICULATES
Model # BAM-3HC
DESCRIPTION:
The BAM-3HC series are
three channel air monitors for simultaneous measuring of gross beta/gamma
particulates and gaseous radioactivity and alpha particulates. Like
all of the BAM-3 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 30 cfm free air and including fine regulation
in the 3 cfm to 10 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; Optional 220
V, 50 or 60 Hz.
