Calibration

The MD 9221 is a professional TRMS AC current clamp meter capable of measuring temperature with a Type K probe, capacitance and frequency. It is equipped with a built-in VFD feature that enables the instrument to measure true values in accordance with frequency. The MD 9221 has a wide range of extra features, including data and MAX hold functions, peak value, auto power off, auto-ranging, relative zero and a 3-phase rotation function. It uses state-of-the-art measurement technology and is housed in a sturdy industrial-grade case.
