Product Description

A general purpose scaler-timer suitable for radioactivity counting utilising Geiger-Muller tubes ; and as a general purpose millisecond digital timing device with manual or electronic triggering. The bright L.E.D. has six digits, 24mm high, making it suitable for individual use or class demonstration. In the radioactivity mode an adjustable 300 to 500V E.H.T. supply for G.M. tubes. Loudspeaker sockets are also provided for use when an audible indication of count rate is required. In the radioactivity mode, the display features ‘most significant figure’ blanking. In the timing mode, the display reads in seconds, i.e. from 0 up to 999.999s, and increments in ms. This provides a clean, unambiguous display. Timing can be actuated manually or by light operated or mechanical switches and also incorporates triggered timing. Supplies of 2V and 6V a.c. at 0.5A are provided via front panel sockets for optical switch light sources, etc.
