DESCRIPTION: The TBM-6U/TBM-6U-SV features
an internally mounted sensitive scintillation detector. The lower
limit of detection (95% confidence level) is 0.7 µR/hr. and
1 µR/hr registers one division on the meter. An LED flash as
well as a beep for each count makes for easier use in dark areas.
Audible and LED visual counts are a sub-multiple of the actual radiations
recorded to allow differentiation at high counting rates. A BNC connector
is provided for addition of an external probe. Internal and external
probe circuits are switch selectable and independently calibratable.
Optional second probe may be any GM, scintillation, or gas flow.
