Ultra High Resistance Meter

(Photo is 5450)


The 5450/5451 is a digital ultra-high resistance meter that loads an I-V converter employing our original variable gain feedback method, a high-precision A/D converter well established in the digital multimeters, and a low-noise high-response voltage source, allowing high-speed and highly-stable adaptation into various high resistance measurement applications.

High resistance measurement can be widely used for testing electrical insulating materials used in secondary cells or semiconductors, electrical or electronic components such as capacitors and print-circuited boards, and synthetic resin or rubber materials in R&D, manufacturing, quality control and/or other fields.

With the use of the fixtures, surface resistivity rate and volume resistivity rate can be measured according to the JIS standards.
In addition, leak current of semiconductor devices with high voltage applied can be measured with high sensitivity and high accuracy.


The measurement mode for the current meter is selectable from high-speed mode, noise-tolerance mode or other modes.
Source/sink output up to 10W at ±1000V
