ΜΕΤΡΗΤΗΣ ΡΑΔΙΕΝΕΡΓΕΙΑΣ Α,Β,Γ,Χ RADALERT-DIGILERT 100

Μετρητής ραδιενέργειας για ακτινοβολία Α, Β, Γ, και Χ

Features a three-second update and a Utility Menu that allows you to change the default settings for several operating parameters. 

Its digital liquid crystal display (LCD) shows the current radiation level in your choice of SI units (microsieverts per hour) from .000 to 1,100 and counts per minute (CPM) from 0 to 350,000 or counts per second (CPS) from 0 to 3,500.

For users of conventional units mR/hr (milliroentgens per hour) from .000 to 110 and CPM are optional in the Utility Menu. 

This instrument also offers an accumulated total and timer function, up to 9,999,000 counts and 40 hours.
