High Precision Decade Megohm Box

Model : 55X-DMB

DESCRIPTION-

“RAI” Model 55X-DMB Decade Megohm Box has been designed for the testing and calibration of insulation testers at voltages of up to 5000 V DC. This high resistance box provides up to eight decades and is designed for accurate high-resistance simulation and calibration applications.

The high resistance decade box is housed in a Pelican (USA) black-colored portable box with carrying handles, providing an ideal solution for on-site as well as laboratory calibration of high-resistance insulation testers, Meggers, insulation bridges, Megohm meters, digital meters, and component comparison.

The resistance range is offered from 100 kOhm to 10 Teraohm, distributed over eight decades. The instrument is suitable for applications where stable, reproducible, and accurately selectable high-resistance values are required for testing and calibration.
