Product Detail
The Surveyor 50's internal components are laid out on modular circuit boards. Span, HV and calibration pots (one for each range) are clearly marked.
The exclusive HV check assures the user the detector is operating at its proper high-voltage (critical for operation near the "edge" of a GM detector plateau).
The anti-saturation circuit keeps the meter reading off-scale when the detector saturates in a high radiation field, providing an added safety margin.
Automatic dead time compensation assures the accuracy of higher exposure rate readings for linear response on all ranges.
A single 9-volt battery powers each instrument. The Surveyor 50 is compatible with all GM probes.
