Digital Portable Meters
Digital Portable Meters (V , I , F , W):-
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.
Feature:
- 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
- High resolution as compared to analog instruments
- No moving parts thus eliminating friction, wear and tear and enhancing life or instruments.
- Distinct readings eliminating ambiguity in readings
- Auxillary supply 20V AC. (Availability) of other ranges is subject to technical feasibility
