Electrical Measuring Instruments

An electrical measuring instrument is a tool for measuring specific numerical values such as frequency, time, and voltage. Work efficiency is improved by displaying the measured values digitally, and it is also useful for professional construction sites. You will find a leak clamp that measures the leakage current and an oscilloscope that can be used for student fieldwork. We also have accessories such as clip adapters, fuses, test leads, and carrying cases that are convenient to carry along with the measuring instrument.
