The best voltmeters in terms of price-performance ratio

When purchasing a voltmeter, you want it to show as accurately as possible. The intrinsic error of the device can affect the calculated values ​​that are important for the operation of the downstream equipment in the circuit. To protect against this, we present for consideration a rating of the best voltmeters, the quality of which fully justifies the cost of the product.

DIGITOP ВМ-3 (color)

Rating: 4.9

The first place in the rating was taken by the Ukrainian product VM-3. The voltmeter is designed for a three-phase network and individually measures the voltage from each line in the range from 40 to 400 V. The controller records the current surges in increments of 1 V. The exact values ​​are provided by an electronic computing circuit that completely excludes the mechanical part. Buyers in reviews praise the product for a small error of 1%, which at a maximum is 4 V and does not affect the performance of the subsequent equipment in the electrical circuit. The housing is mounted on a DIN rail and takes up little space in the shield. Connecting wires is as safe as possible, since live parts are deeply hidden.

Our experts included the voltmeter in the rating for the three-color display of the result. The values ​​for each phase are displayed in white, blue and red against a black background. This is not only clearly noticeable, but helps the electrician to immediately understand on which line the voltage drop is, and to narrow the search for a leak.
