1 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. Th is timer has a TNC connector for connecting a GM tube; RAD-340-150 is a compatible GM tube to use with this. Timer : 4 Auto Ranges (0 to 9.999s, 10 to 99.99s, 100 to 999.9s & 1000 to 9999s) Scaler : 3 Auto Ranges (0 to 9.999x1000, 10 to 99.99x1000 & 100 to 999.9x1000 counts) Accuracy : ±0.01% Sensitivity : 160mV peak Ratemeter : 3 Auto Ranges (0 to 9.999x1000/s, 10 to 99.99x1000/s & 100 to 999.9x1000/s) Frequency Meter : 3 Auto Ranges (0 to 9.999kHz, 10 to 99.99kHz & 100 to 999.9kHz)
