The IET Labs GR 1455 Kelvin-Varley Voltage Dividers provide accurately known voltage ratios from 0.00001 to 1.00000 for use in many common measurements:
1. Voltage gain or attenuation
2. Linearity of potentiometers and other controls
3. Frequency response of audio and rf networks
4. Transformer turns ratio
5. Voltmeter calibration
A resistive divider of the Kelvin-Varley type, the 1455 has precision resistors throughout (rather than in selected positions only) for over-all high accuracy. Linearity is as low as 0.02 ppm of input.
Models: 1455A 10 kΩ €8.596, 1455BH 100 kΩ €10.296.
