72 mm AC Panel Voltmeter
The Unique-Bargains SQ72 is a screw-mounted analog panel meter for AC voltage measurement. Its 72 by 72 mm face fits standard display and switch panels in control and power-distribution systems. The instrument targets installers and technicians who need a direct-reading meter for fixed installations.
Class 1.5 accuracy across 0-600 V
Accuracy remains at Class 1.5 throughout the full 0 to 600 V range rather than only at a single point. The scale can be re-calibrated through the front adjuster without removing the frame, so long-term drift can be corrected in situ. This behaviour suits continuous monitoring where periodic verification is required.
Passive operation with screw terminals
The movement draws negligible power from the measured circuit and requires no auxiliary supply. Two screw threads, 2 mm and 4.5 mm diameter, secure the case to the panel. No fan or active cooling is present, so the meter adds no audible noise or heat to the enclosure.

Questions about this item
How much heat does the SQ72 generate when running continuously on a 600V AC circuit?
The analog movement draws only the tiny current needed to deflect the needle, so it adds negligible heat to a panel even during all-day operation.
What mounting hardware must I already have to install the 72mm SQ72 in my panel?
You need a 72 x 72mm cut-out and screws to match the 2mm and 4.5mm thread diameters supplied with the meter.
Will the Class 1.5 SQ72 read accurately alongside older 0-600V analog meters already in my switchboard?
Its Class 1.5 accuracy means readings stay within 1.5% of full scale, so it tracks consistently with other 0-600V meters of the same class in the same cabinet.
