Tinsley 4721 High Resistance Single Decade Box 5000V DC
The Tinsley Model 4721 decade box is designed for the checking and calibration of insulation testers at voltages of up to 5000V DC.
The total range covered is from 1 kΩ to 1TeraΩ using specially selected resistors and a high quality switch mounted on an easy to read panel.
This resistance box is housed in a strong aluminium case with lid and carrying handle to provide an ideal solution to on-site and laboratory calibration of high resistance insulation testers.
The instrument can be supplied complete with a calibration certificate provided by our own in-house calibration laboratory.
