Resistance decade boxes are high
accuracy
With a resistance range from 0.001 to 11megaOhm and an accuracy of 0.01% across the eight-model series, the Cropico Decade Boxes are incorporated in a ruggedised lightweight metal case
Precision measurement specialist Cropico supplies a versatile range of resistance decade boxes The company's range includes a series of 5, 6 and 8 decade boxes which have been designed to provide highly accurate and variable standard values of resistance and current for calibration, comparison and test applications in the laboratory or workshop

The Cropico range of high accuracy digital temperature indicators has been designed to set new standards of measurement flexibility
Gold plated brass contacts on the switches ensure low contact resistance and negligible thermal EMF.
The resistor windings comprise an exclusive air cushioned technique that provides virtually stress free elements for improved performance.
The elements are non-inductively wound and the direction of each winding is reversed at the half turn points.
Long term stability makes the units ideal for precise resistance thermometer and insulation simulation.
Some models in the 005/6/8 range use the Waidner Wolf technique to ensure high accuracy measurements of low values and with resolution as low as 0.001Ohm, the Cropico decade resistance boxes are particularly suited to PT100 simulation. Request a free brochure from Cropico ...
