KOHGIKEN CO.,LTD.

We manufacture and sell diagnostic equipment that uses harmonics to detect abnormalities and deterioration of electrical equipment (motors, inverters, etc.). The use of this diagnostic instrument enables predictive and preventive maintenance of electrical equipment, thereby preventing unexpected accidents.
We also sell our products to companies in China, Korea, and Taiwan, with distributors in China and dealers in Korea.

Harmonics are produced when equipment has abnormalities or deteriorates. Using a search coil, we can investigate the state of equipment by quantifying the harmonics from the 2nd to the 40th order through an FFT (Fast Fourier Transform) and analyzing the results based on data accumulated over many years. AC motors, inverters, and load-bearing parts of electrical equipment can all be diagnosed. We also automatically propose countermeasures for abnormal or deteriorated equipment via the server.
Our product lineup is as follows.
(1) KS-3000 Model A
(2) KS-2000 A
(3) Centralized management system for condition monitoring (multi-sensor design)
