Scaler Timer Frequency Meter Ipc. A multi-purpose instrument, combining the functions of multi-purpose timer, ratemeter and frequency meter in one compact unit. It can be used as 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 TNC socket, TNC-to-BNC adaptor is required for connecting GM tube with BNC plug.Timer Four Auto Ranges: 0 to 9.999 s, 10 to 99.99 s, 100 to 999.9 s, 1000 to 9999 sScaler Three Auto Ranges: 0 to 9.999 1000 counts, 10 to 99.99 1000 counts, 100 to 999.9 1000 countsAccuracy: ±0.01%Sensitivity: 160 mV peakRatemeter Three Auto Ranges: 0 to 9.999 1000/s, 10 to 99.99 1000/s, 100 to 999.9 1000/sFrequency Meter Three Auto Ranges: 0 to 9.999 kHz, 10 to 99.99kHz, 100 to 999.9 kHzMax Input Signal: 20 rmsMax Sensitivity: 250 mV rmsRange: 10 Hz to MHz
