Hioki SR2 [SR-2] Standard Resistor Calibration Box for Super Megohmmeters

Hioki Super Megohmmeters are high insulation resistance meters designed to measure the electrical resistance of insulation materials with high insulating properties. The SR-2 is for calibrating various types of super megohmmeters, consisting of 24 ultra-precision resistors encased in a sealed metal case. Each element can be connected on the terminal plate in various combinations as required.

This is a resistor box for calibration of the super megohmmeters.
Max. voltage is 1000 V DC and resistor value covers from 1 M to 10,000 MΩ in 24 points.
