Product Introduction

FYFS-2002 series automatic low background multi-channel gamma spectrometer is a new generation of low background γ radiation detection equipment independently developed by Hubei Fangyuan Environmental Protection Science & Technology Co., Ltd.

Functional Features

1. Lead chamber:

＊ Five layer lead chamber with new structure, detector crystal thickening protection (lead equivalent thickness 160mm) (patented technology)

＊ Background ＜180cpm (3cps)

＊ Lead equivalent thickness: 100mm,  inner diameter:220mm,  outer diameter: 440mm

2. Multichannel analyzer:

＊ Fast pulse shaping and filtering technology (patent technology)

＊ 1024 / 2048 / 4096 channels optional on software

＊ USB / serial port optional

＊ Ultra low power consumption, host power < 20

3. Analysis software:

＊ The software system v1.0 (software copyright) of full-automatic low background multichannel gamma spectrometer analysis for square and circle.

＊ Automatic spectrum collection, automatic peak seeking function, mouse operation, easy to use

＊ According to the GB6566-2010, the radionuclide content and internal and external exposure index are calculated automatically

＊ Sampling method: fixed time sampling and fixed number sampling

＊ Fixed time sampling: optional measurement time 0-200000 s

＊ The measurement duration can be changed during the measurement process

＊ Under the condition of unknown sample activity, enough spectral lines can be obtained by setting the total capture count

＊ Types of analytical nuclides: RA, th, K, RN. (other nuclides such as u, CS, CO can be added according to user requirements)

＊ The power-off spectral line is automatically saved, and the instrument can automatically save the current measured spectral line in case of power failure and other emergencies during the measurement process

＊ Breakpoint continued acquisition: for the spectrum lines that have not been collected, the 

software can be transferred into the current spectrum line to continue the acquisition

＊ Sampling completion alarm: after the current acquisition, there will be an audible alarm prompt

＊ Continuous sampling and single sampling: you can switch between continuous sampling and single sampling. The number of spectral lines for continuous sampling can be set according to needs

＊ Information detection before printing: before printing the report, check the spectral line information, or modify and fill in the spectral line information (the measurement result cannot be changed)

＊ Print preview: preview the print interface before printing

＊Advanced functions: support spectral filter length modification, correction coefficient modification, and hybrid calculation.

＊ Support login user name and password modification, support spectral channel address conversion

＊ Support double-click the spectral line file to open the software and call in the current spectral line

＊ The general calculation results are saved automatically to ensure the uniqueness and traceability of the results
