Features
Small Digital Ratemeter with separable 2” diameter pancake probe. Reads out in mR/hr (Optional mSv/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.
