The Klein CL800 Multimeter is a professional-grade, self-ranging digital device with auto-ranging capability. It features enhanced AC/DC voltage, continuity, frequency and capacitance testing capabilities, along with temperature measurements. Equipped with an integrated, low-impedance mode, it prevents false readings from residual or ghost voltage. The device comes with a thermocouple probe, batteries, and a carrying pouch. Its True RMS function ensures accurate measurements regardless of waveform shape or distortion levels.
