SPECIFICATION

Portable Digital Ammeters, Voltmeters, and Frequency meters are designed for AC, DC, and True RMS measurements. Single-phase Portable Digital Wattmeters can measure power in single-phase systems with a 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. The display is a bright red LED. There is no confusion about the 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 instruments are much lighter in weight and easy to carry. These instruments are ideal for educational institutes.

FEATURES:

  • 3½ Digit Bright Red LED Display 1999 (max) for Volts, Ampere, and Low Power Factor Wattmeters
  • 4 ½ Digit Bright Red LED Display. 19999 (max) for Unity Power Factor Wattmeters
  • 3 Digit Brigit Red LED Display. 999 (max) for frequency meters
  • Light, Compact Sleek Design
  • Accurate Readings
  • High resolution as compared to analog instruments
  • No moving parts thus eliminating friction, wear and tear and enhancing life or instruments.
  • Distinct readings eliminate ambiguity in readings
  • Auxiliary supply 20VAC. (Availability) of other ranges is subject to technical feasibility
