توضیحات محصول
Fields of application
Fire Brigades, Civil Defence, Authorities, Industry
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)
- all functions are secured by a password
- integrated data storage, internal software adapted to fire brigades requirements
- additional alarm threshold at triple background count
- 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
