Portable Digital Ammeters, Voltmeters and Frequency meter are designed for AC, DC and True RMS measurements, Single phase Portable Digital Wattmeters can measure power in single phase systems with unity power factor (P.F. = 1.0) and Low Power factor (P.F. = 0.2). These instruments are more rugged, reliable and accurate than analog meters, They are light in weight , compact in size and stylish in design. They do not have any moving parts. Display is bright Red LED’s. There is no confusion of anti parallax scale.
A Single instrument covers a wide range, (as compared to analog meters) reducing the number of instruments required, thus saving cost and space. These instrument are much lighter in weight and easy to carry. These instruments are ideal for educational institutes.
