ZK-2717 precision standard inductance box

  1. ZK-2717 precision inductance box has 1x and 5x alternating step sizes in inductance change and is an ideal standard inductance measuring instrument with a wide inductance range, high performance, good stability, small volume and light weight. It is suitable for measurement laboratories, research institutions, production, and particularly suitable for field calibration/verification of RLC measuring instruments and special inductance measuring instruments in factories, and has the following main features:
  2. 1.This inductance box is first time to combines network simulated inductor with toridal-core inductor. It has high accuracy, small volume, and light weight;
  3. 2.It has excellent electromagnetic shielding, vibration prevention and moisture proofing technique to provide extreme stabile performance;
  4. 3.This inductance boxis first time to combines network simulated inductor with toridal-core  inductor. It has high accuracy, small volume, and light weight.
