    DIGITAL PORTABLE AMMETERS, VOLTMETERS, FREQUENCY METERS
Model : R-3501P
FEATURES

 

"MECO-G" Portable Digital Ammeters, Voltmetrs and frequency meters are designed for AC, DC and True RMS measuremnet. Single Phase Portable Digital Watttmetrs can measure poer in single phase system 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 instrument required, thus saving cost and space. These instruments are much lightter in weight and easy to carry. These instruments are ideal for educational institiutes.

  • 3½ Digit Bright Red LED Display, 1999 (max) for Volt, Ampere and Low Power FactorWalttmeters
  • 3 Digit Bright 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 enhancing life of instruments
  • Distinct reading eliminating ambiguility in readings.
  • Auxiliary supply 230V AC. (Availability of other ranges is subject to technical feasibility)
