Calibrator NK4-1

Calibrator DC NK4-1 is a unique measurement tool designed for testing of low currents and high resistances.

That device allows to perform a verification at the test voltage at the output of the device under verification from 1 to 1000 V.

It can be used as a highly stable current source.

Range Overview

The scope of use of calibrator has significantly expanded due to the presence of some additional functions, such as tension reproduction and measuring DC voltage with high input impedance.

The built-in IEEE-488 interface provides remote control of the device.

A wide range of the latest features and functional flexibility of the device provides flexibility, efficiency and ease of use.
