Scaler Timer Frequency Meter

A multi-purpose instrument, combining the functions of a multi-purpose timer, ratemeter and frequency meter in one compact unit. It can be used as a simple stopwatch to more sophisticated applications such as dynamics experiments with air tracks etc. The scaler and ratemeter modes allow numerous radioactivity experiments to be undertaken. It has four, 7-segment LED digits 13 mm high. The high brightness and large size display make it ideal for classroom demonstrations. The microprocessor based design minimises the number of controls required and these are clearly labelled so that the instrument is very straightforward to use.

The GM tube input is a TNC socket, TNC-to-BNC adaptor is required for connecting GM tube with BNC plug.
