Measuring instruments AMA-801, AD-G31, VMA-801, etc.

Analog ammeters
Analog electrical measuring ammeters of the trademark are designed to measure the current in alternating current electrical circuits. The devices are used to work indoors, in electrical switchboard equipment, in electrical installations of industrial enterprises, residential, public buildings and structures. Ammeters are installed on the panel of the shield (square and round cutouts). The dimensions of the instrument panels are 72 x 72, 80 x 80 and 96 x 96.

Digital ammeters
Digital electrical measuring ammeters of the trademark are designed to measure the force in single-phase and three-phase AC electrical circuits. The devices are used to work indoors, in electrical switchboard equipment, in electrical installations of industrial enterprises, residential and public buildings and structures. Ammeters can be either direct or transformer connected. The measuring range of transformer connection devices depends only on the nominal value of the connected current measuring transformer. The microprocessor device of the devices allows you to obtain an accuracy class of 0.5, which is many times higher than the accuracy class of analog ammeters.

Analog voltmeters
Analog electrical voltmeters of the trademark are designed to measure voltage in AC electrical circuits. The devices are used to work indoors, in electrical switchboard equipment, in electrical installations of industrial enterprises, residential, public buildings and structures. Voltmeters are installed on the panel of the shield (square and round cutouts). The dimensions of the instrument panels are 72 x 72, 80 x 80 and 96 x 96. Voltmeters can only be directly connected, the measurement range depends on the selected modification of the voltmeter. The accuracy class of Analog voltmeters is 1.5 for square and 2.5 for round cutouts, respectively.

Digital voltmeters
Digital electrical voltmeters of the trademark are designed to measure voltage in AC electrical circuits. The devices are used to work indoors, in electrical switchboard equipment, in electrical installations of industrial enterprises, residential, public buildings and structures. Voltmeters are installed on the panel of the shield (square cutout). The dimensions of the instrument panels are 72 x 72 and 96 x 96 mm. Voltmeters can be either direct or transformer connected. The measuring range of transformer connection devices depends only on the nominal value of the connected current measuring transformer. The microprocessor device of the devices allows you to obtain an accuracy class of 0.5, which is many times higher than the accuracy class of analog voltmeters.

Analog AMA-721 ammeter with interchangeable scales
The AMA-721 analog ammeter with interchangeable scales is designed to measure the current in alternating current electrical circuits. The devices are used to work indoors, in electrical switchboard equipment, in electrical installations of industrial enterprises, residential, public buildings and structures.

Multifunctional meters
The multifunctional measuring device is a digital programmable device designed to measure the parameters of three-phase 3- or 4-wire networks with symmetrical and unbalanced loads with simultaneous display of measured values and digital data transmission. The device makes it possible to control, analyze and optimize the operation of power equipment, systems and industrial circuits. The device allows you to measure the following parameters: RMS values of current and voltage, frequency, active, reactive and total power, active and reactive energy in the forward and reverse directions; power coefficients, frequencies; averaged active and reactive power; harmonics; harmonic distortion coefficient; peak values.

Analog AMA-961 ammeter with interchangeable scales
The AMA-961 analog ammeter with interchangeable scales is designed to measure the current in AC electrical circuits. The devices are used for work in enclosed spaces, in switchboard equipment, in electrical installations of industrial enterprises, residential, public buildings and structures.
