Description

The Mastech Clamp Meter is a reliable, handheld electrical measuring device designed to measure AC current without the need to disconnect wires. Mastech models, such as the M266 and MS2001, feature a jaw clamp that detects current using electromagnetic induction. They also support measurements of voltage (AC/DC), resistance, continuity, and sometimes frequency. Known for their durability, affordability, and ease of use, Mastech clamp meters are popular among electricians, solar technicians, and electronics hobbyists.
