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.

Key Features

  • Wide resistance range up to 10 TΩ (depending on model)

  • Rated for high-voltage insulation calibration up to 10 kV

  • Precision resistors with low temperature coefficient

  • Switchable decade steps for resistance selection

  • High insulation and low leakage design

  • Fully shielded metal enclosure

  • Portable and maintenance-free construction

  • Ideal for calibration laboratories and service departments
