LCD type meter capable of measuring harmonics and waveforms ★★★ Instruments for distribution boards, control panels, distribution panels, and panels.
This is a product that assists in managing harmonics on-site. It displays data comparing previous and current states through harmonic limit settings and data storage for input current. When the limit values for each order are exceeded, it automatically notifies or outputs control signals. For inquiries, please contact "lightstar_1979@yahoo.co.jp".

Company information
Our company was founded in 1979 and has grown from producing early analog (needle-type) instruments to digital instruments, as well as products that allow for the observation of electrical data via wireless and the internet. This development reflects the strong commitment of our employees to walk alongside our customers. Additionally, we are making proactive investments in technology development at our affiliated research institute and are thoroughly operating our business processes with a customer-centric approach. We are dedicated to meeting the diverse needs of our customers through more differentiated services. In our case, we have become well-known in South Korea for our measuring instruments (analog, digital meters, and CT, VT). We have been exporting to Japanese companies for over a decade, and we have registered with Ipros to introduce our products to more Japanese customers. In 2022, we registered as a corporation in Tokyo and have since relocated our corporate office to Osaka under the name "LIGHTSTAR JAPAN." We also have Japanese staff on-site, and we look forward to serving you.
