Radioactive Surface Contamination Ndt Testing Instruments With One Probe

detecting area: 180cm² Radioactive surface contamination instrument with one probe

Introduction
FJ39-2180 α,β Measuring instrument is suitable for the low levels α,β Radiation surface contamination detection.The instrument adopt double flash detector,has the high detection efficiency; The same probe can measure at the same time α,β,γ,And automatically distinguish among α,β,γ, and particles and radiation dose rate, is the environment, nuclear medicine and molecular biology lab, radiation chemistry, nuclear materials transportation, storage, and the inspection of areas such as alpha, beta radiation surface contamination detection of the ideal instrument.

Features
1) Counter jam alarm prompt and protection function
2) To separate α,β/γ measurement, optional alpha nuclide identification
3) Built-in high capacity lithium battery, real-time display battery capacity
4) Detector adopts double crystal, high sensitivity, fast response speed
5) Function of background light, convenient and insufficient light environment in the night
6) Large size lattice liquid crystal display, measurement results show that the clear and intuitive
7) Touch key, easy and convenient operation

8) Meet the national standards of various alarm threshold selection, and also can define itself 9) 4 GB of large capacity storage can store 100000 groups of data for check at any time, data printing, can
communicate with the upper machine (with analysis software)
10) The host connected to the probe cable can be extended to 1.5 km, can also be used for wireless
docking
11) Host built-in GM detector, real-time monitoring operators around the environment
12) IP65 The whole machine IP65 waterproof effect
