Features
- efficient, portable contamination monitor with thin-layer plastic scintillation detector completely working without gas-filled or
gas flow proportional detectors - measurement of alpha, beta and gamma radiation with only one detector (the measuring system automatically detects the existence of alpha radiation)
- possibility of simultaneous or selective measurement of α- and
β-/γ-contaminations - easy-to-use (convenient operation with 5 membrane-switch arrays)
- settings and important measurement parameters are secured
by a password - integrated data storage, optional software for reading out and processing this measuring data
- connection facility for different external probes,
e.g. for dose rate measurement - automatic probe identification
- optional stationary use in wall station with voltage supply
- a mechanically defective detector foil can be repaired by the user himself (no expensive detector repair required by the manufacturer
as otherwise customary for xenon detectors) - avoiding high costs for gas flushing
