Tunkia and Its Approach to Electrical, Magnetic and Material Measurement Technologies

The Origin of Tunkia

Tunkia was founded with a clear focus on developing equipment for electrical measurement, magnetic measurement, and material testing. From its R&D center to its manufacturing facilities, the company concentrates on creating instruments with high stability and repeatability — qualities that are essential for calibration laboratories, research institutes, and industrial production environments.

Throughout nearly two decades of development, Tunkia has gradually expanded its product portfolio while maintaining a consistent direction: prioritizing core technologies rather than pursuing sheer product quantity.

How Tunkia Expanded Its Measurement and Testing Capabilities

Starting with electrical measurement and signal calibration

In its early stages, Tunkia focused on standard sources and signal simulation equipment. From basic AC/DC voltage and current generation, the company moved toward developing solutions for testing power meters, evaluating power quality, and assessing measurement accuracy. These technologies became fundamental tools for energy calibration labs and manufacturers of metering devices.

Advancing into magnetic measurement and sensor calibration

As demand increased in research fields and magnetic component testing, Tunkia expanded into magnetic measurement. The company introduced gaussmeters, fluxmeters, Hall and Fluxgate sensors, along with controlled magnetic field generation systems for calibration. This step positioned Tunkia among the few manufacturers capable of providing magnetic measurement tools from basic to advanced levels.

Applying measurement technology to magnetic material and electrical steel testing

Building on its magnetic expertise, Tunkia developed systems for evaluating magnetic materials, including iron loss analysis, flux density, and characteristics of silicon steel, soft magnetic materials, and hard magnetic materials. These instruments are used widely in motor production, transformer manufacturing, and materials research.

Entering the field of new energy and EV charging testing

In recent years, Tunkia has added EV charging test equipment and meter verification systems. These devices simulate charging loads, analyze charging performance, and support the rapid growth of the electric vehicle industry.
