DecR Series High Voltage Decade Resistance Standard
The DecR Series is a precision high-voltage decade resistance standard designed for the calibration and verification of insulation testers, megohmmeters, and other high-resistance measuring instruments. Built with low-temperature-coefficient resistors and shielded construction, it ensures stable and accurate resistance values even under high-voltage stress. The robust design makes it ideal for laboratory calibration as well as field verification applications.
