Beschreibung

The IET Labs RV722 standards grade Kelvin-Varley voltage divider is highly accurate, stable, and linear instrument for use in many applications requiring accurately known voltage or current ratios.
In particular, the RV722 is especially appropriate for use in bridge circuits, providing two arms of a bridge with a very well known ratio.
Applications include linearity determination, the measurement of voltage and resistance, and the calibration of voltage, current, and resistance.

•Primary Calibration grade 100 kΩ Kelivin-Varley Voltage Divider
•Used by National Measurement Institutes around the world
•Built in Wheatstone Bridge allows for a self calibrating circuit
•Employs „Hermetically Sealed Wire Wound Resistors“
