Scaler Timer Frequency Meter

A multi-purpose instrument which is invaluable in the physics laboratory, combining the functions of a multi-purpose timer, a ratemeter and a frequency meter in one compact unit. It has four, 7-segment LED digits, 13mm high. The high brightness and large size display make it ideal for classroom demonstrations. It can be used as a simple stopwatch or more sophisticated applications such as dynamics experiments with air tracks etc. The scaler and ratemeter modes allow numerous radioactivity experiments to be undertaken. When used as a frequency meter the instrument will accept diversified waveforms and may be used to determine the rotational frequency of a stroboscope disc and for displaying the frequency of a waveform from a signal generator. The instrument can be pulse operated to enable moving bodies to be timed using photo-timing gates. When used as a scaler or ratemeter the input signal can be via either a GM tube or a solid-state detector (mostly obsolete now) with an audio output. Housed in a robust metal case with a durable powder coated finish. This timer has a TNC connector for connecting a GM tube; RAD-340-150 is a suitable GM tube to use with this.
