Analog Panel Meter
The Sigma SA-72 Analog Panel Meter meets TS 5590 and EN 60051-2 standards. It’s built for precise AC current and voltage measurements in electrical panels. It works on the moving-iron principle and has a 90° deflection. The clear analog scale makes it easy to read from far away. Available in 72×72 mm and 96×96 mm sizes. It connects directly for low ranges. For higher currents, it uses a current transformer. Its exchangeable scale and protective polycarbonate back cover ensure flexibility and safe operation.

Applications and Uses
This AC ampere meter is installed where consistent visual monitoring of electricity matters. Here are some practical applications:
- Switchboards and Control Panels: Often used in industrial setups, they monitor incoming AC mains or feeder loads.
- Generator Panels: Great for local generator control boards that need a basic AC voltmeter (0-300V) or ammeter readout.
- Machinery Monitoring: Good for panels on production machines. Operators can quickly check if a motor uses the right current.
- Power Distribution: Used in AC current panel meters in LT distribution boxes in commercial buildings in Lahore.
- Solar System Displays: Shows solar watt meter readings in a simple line format. Use it for quick string current checks—no complicated digital setup needed.

FAQs
What is an analog panel meter?
An analog panel meter measures electrical values like AC current or voltage. It displays the results with a needle moving across a marked scale. There is no digital display, making the reading immediate and visual.
Which is the better choice for me, a digital meter or an analog meter?
It really depends on the job. A digital meter gives you a precise numerical value. An analog meter, like this AC amp-meter digital alternative, shines when you need to observe a trend at a glance, like noticing a quick needle fluctuation that a digital screen might show as just jumping numbers. The Sigma SA-72 does not require a separate power supply to display the reading, which is a key difference.
What are the main advantages of using these analog meters?
The practical advantages are their straightforward nature and durability. They offer good vibration resistance and a clear reading on larger distances. For many analog AC ammeter price-conscious projects in Lahore, these instruments provide essential measurements without any software or electronic complexity.
