Panel and modular voltmeters

Analog panel voltmeters are traditionally used to measure voltage in various panel-mounted equipment. Their advantages include simplicity, reliability, and clear display of information.
ETC "Joule" produces panel voltmeters in standard sizes of 48x48, 72x72, 96x96, and 144x144 mm. Improved instruments for three-phase networks are equipped with a phase switch, allowing a single voltmeter to measure six voltages (three phase-to-phase and three phase-to-phase). Upon customer request, instruments can be manufactured in a special tropicalized version.
ETC "Joule" electrical measuring instruments are included in the Russian Federation Registry of Measuring Instruments under No. 61894-15 and are verified using standard methods
