The Klein Tools CL390 is an exceptionally versatile electrical measuring tool. Thanks to its TRMS (True RMS) technology with auto-ranging, this digital clamp multimeter is capable of precisely measuring various essential electrical quantities.

Its main feature is the ability to measure alternating and direct voltage (AC/DC) using its clamp, but it doesn't stop there. Indeed, the CL390 digital clamp meter can also measure AC/DC voltage, DC micro-amps, resistance, continuity, frequency, capacitance as well as diodes using test leads. Additionally, its ability to measure temperature using a thermocouple probe makes it a complete tool for many applications.

Equipped with a high-quality reverse contrast LCD display, the CL390 clamp digital multimeter guarantees optimal visibility in all circumstances, whether in dimly lit or very bright environments. Its ergonomic and intuitive design makes it easy to handle, providing user-friendly use even for users new to electrical measuring devices.

Whether for industrial, commercial or residential applications, the Klein Tools CL390 True RMS clamp meter stands out for its reliability, precision and versatility. Thanks to its multiple features and its manufacturing quality, this electrical tester is a great ally for all professionals and amateurs looking for a high-performance tool for their electrical measurement needs.
