IET is the World's Leading Resistance Decade Box Manufacturer With 50+ years of stability data and history, IET Labs manufactures a full line of resistance decade boxes that will cover most any budget and application: field, calibration laboratory or automated test stations.
From the world's highest precision to our cost-effective models, 1000's of models are available from 1 mΩ to 10 TΩ.
Programmable and self-calibrating models are also available to automate your resistance decades.
Contact us if you don’t find the decade resistor you need and we would be happy to design a custom decade to your requirements.
Almost all of IET’s resistance decade boxes are manufactured with pride in the USA.
PRS-330 Precision Programmable Resistance Box & RTD Simulator
Resistance range: 0.1 Ω to 20 MΩ with a Resolution of 1 μΩ or 6 digits Lab grade accuracy (70 ppm + 1 mΩ): 1.5 times better than conventional manual decade resistors Manual or Programmable resistor with USB, Ethernet and IEEE interfaces all standard Very low long term maintenance cost- with an 5 year warranty About 10% lower in cost to the PRS-370 If you own 8.5 Digit DMM (Fluke 8508A, 8588A or Keysight 3458A) you should strongly consider the PRS-370 .
