Tronic Three Phase Guide Rail Voltmeter 80-500V AC
TSh 46,500
Our review
This Tronic unit is a guide-rail mounted voltmeter built to read voltage across three-phase systems within an 80 to 500V AC range. It suits electricians, maintenance teams, and facility managers who need a permanent, panel-mounted way to keep an eye on supply levels in industrial plants, commercial buildings, manufacturing floors, or distribution boards. Because it clips onto standard guide rail, it fits neatly into existing switchgear layouts rather than needing a separate enclosure. Before buying, confirm your system voltage falls inside that 80 to 500V AC window and that your panel uses compatible guide-rail mounting. It is worth comparing against handheld or panel-meter alternatives: a fixed rail unit like this is better for continuous monitoring, while portables offer more flexibility for spot checks. Also check whether you need just voltage display or additional functions, since this model focuses on voltage measurement alone. If your setup matches, it is available on Sokonia.
