Product Description
RS PRO 186-2491 is a high-quality DC analogue voltmeter designed for precise measurement of DC current up to 30 amperes, featuring a moving coil mechanism with 1% accuracy. The instrument is housed in a compact 68 mm by 68 mm square polycarbonate case, tailored for easy installation within industrial control and switchgear panels.
The meter’s design includes permanent magnet moving coil movements with an aluminum coil suspended on pivots supported by a hairspring and jewel mechanism, providing smooth and accurate pointer movement across a linear, calibrated scale starting at zero. The knife-edge type pointer deflects from 0° to 90°, delivering clear visual readings.
The instrument supports a DC voltmeter nominal range of 15 mV to 600 V and allows measurement of currents up to 30 A DC using separate shunts connected to the rear. It features shock resistance up to 15 g for pulse durations of 11 milliseconds, and continuous overload capacity at 1.2 times nominal voltage, enhancing meter durability in demanding industrial environments.
Operating temperature range extends between -10 °C to 65 °C, with storage temperatures from -25 °C to 75 °C. The voltmeter is IP52 rated for protection against dust and dripping water, and meets multiple international standards and certifications including UL 94 V-0, 2014/35/EC Low Voltage Directive, 2014/30/EC EMC Directive, VDE 0100-410, IEC 61010, and ISO 20653 among others, ensuring safe and compliant operation.
The meter is built with a molded polycarbonate case, suitable for rugged industrial and laboratory panel mounting applications. Its compact size (68 mm x 68 mm cutout and 67 mm depth) allows space-efficient panel design without sacrificing display clarity.
High accuracy and shock resistance extend its utility in HVAC, manufacturing, water treatment, and electrical systems monitoring. It is ideal for applications requiring precise AC/DC voltage and current measurements in automation and process control industries.
RS PRO’s 186-2491 model offers reliable performance for industrial construction, electrical panel instrumentation, and laboratory use. Explore more products in RS PRO Voltmeters and panel meters category on EnvMart for your industrial instrumentation needs.
