Sonel Test & Measurement

Sonel Test & Measurement is a product division of Sonel S.A., a Polish manufacturer of electrical measurement and testing instruments with a broad presence in European and international markets. The brand produces specialized instruments for electrical infrastructure inspection, including light meters, ultraviolet corona detection cameras, and thermal imaging cameras used in the maintenance of high-voltage power systems.

The UV-260 corona detection camera is designed for non-contact identification of corona discharge and partial discharge activity in high-voltage equipment — including overhead transmission lines, substations, and switchgear — without requiring de-energization. Light meters in the LXP series provide precise photometric measurements for illumination assessments in industrial, commercial, and public facilities.
