Unique-Bargains 85L1 AC 0-1A analog panel ammeter electrician tool

Product identity and target use

This Unique-Bargains 85L1 is an analog panel ammeter designed for AC current measurement from 0 to 1 ampere. It suits electricians, panel builders and hobbyists who need a direct-reading gauge for switchboards, test benches or control cabinets. The meter connects directly without an external shunt, simplifying wiring in low-current AC circuits. Class 2.5 accuracy meets general monitoring requirements where laboratory precision is not required.

Sustained-load behaviour

The movement maintains its Class 2.5 accuracy across the full 0-1A range during continuous operation. Damping response settles in less than 4 seconds, so the needle stabilises quickly after load changes and remains steady during prolonged use. Withstand voltage of 2000V for one minute confirms the insulation holds under normal working voltages without degradation. Operating temperature spans -10°C to +55°C, allowing reliable readings in unheated enclosures or warm equipment rooms.

Thermals, noise and power

As a passive analog instrument it draws no auxiliary power and generates no audible noise. The movement produces negligible self-heating, so panel temperature rise is minimal even when mounted in groups. Net weight is 112g, adding little mass to the panel assembly. Thread diameters of 3mm and 4mm accommodate standard mounting hardware supplied in the package. Panel cut-out dimensions of 63 x 55 x 10mm fit common DIN-style openings.
