DESCRIPTION: Small three range
Ratemeter with separable 2'' diameter pancake probe. Reads out in
counts per minute ( and mR/hr). Thin probe window is recessed and
protected by sturdy stainless steel grill. Instrument will see alpha,
beta and gamma radiation. Anti-saturation circuit will not fall below
full scale in high fields. Tested to 100 R/hr. Sonalert with volume
control gives audible rate indication.
APPLICATION: Its small size, light
weight, separable probe and large detector area make this a very useful
monitor for surveying bench tops or checking hands, clothes and fingertips
for almost any radioactive contamination.
