Milli-ohmmeter MIKO-8M

Resistance measurement in inductive and non-inductive circuits in the range of 1 μOhm ÷ 10 kOhm


The MIKO-8M(A) milliometer is developed to measure DC resistance in the range from 1 µOhm ÷ 10 kOhm for the current of up to 10А for: Windings of power and measurement transformers, windings of electric motors, generators, linear compensators and windings of other high-inductance equipment; Contacts of circuit breakers, resistors, buses and other inductance-free circuits; Equalizing, current limiting and other resistors of high-voltage circuit bre­akers; Сables. The device provides a fully automated process of measuring the resistance of a high inductive load and compensation of thermoelectric power in the external circuit.

Key Features

MIKO-8M(A) implements specialized measurement modes for various configurations of 10 objects (resistive object, inductive, voltage transformer, current transformer and power transformer, generator, motor, compensator, connection filter and magnet), taking into account their specific features, while The user can select a typical object from the proposed list or create his own object. The instrument automatically takes into account the configuration of the object for adjusting the measuring modes.

High level of protection and safety conformity

MIKO-8М(A) has the safety certificate IEC 61010-1. The instrument also meets the requirements of electromagnetic compatibility that are applied to class A instruments according to IEC 61326-1.

Touch screen, remote control and bluetooth data transfer

MIKO-8M(A) is equipped with a color graphic touch screen display of high brightness and an intuitive interface, which facilitates interaction with the device.
