FEATURES:
- LIGHT WEIGHT
- ONE HAND OPERATION (CLEVER PROBE HOLDER)
- NO RANGE SWITCHING
- DETACHABLE PANCAKE PROBE
- BUILT-IN SONALERT
- ANTI-SATURATION CIRCUIT
DESCRIPTION: Small Digital Ratemeter with
separable 2'' diameter pancake probe. Reads out in mR/hr (Optional
µ Sv/h or cpm, cps. 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 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.
See ``Beta Pancake Response'' specification
(BETA PANCAKE RESPONSE)
