Product Introduction:

Double Clamp Digital Phase Voltmeter, also known as single-phase phase voltammeter, digital phase voltammeter, voltammeter, phase measuring instrument, is used for phase, AC current, AC voltage, AC leakage current, and phase sequence measurement.

The AC voltage and AC current can be directly measured when the circuit under test is not open, and the phase between the two voltages, the two currents, and the voltage and current can be measured.

In addition, the power factor and power of the circuit can be indirectly measured, and the three-phase phase sequence, transformer wiring group, inductive, capacitive circuit, test the secondary circuit and the female difference protection system, read out the phase relationship between the CT of the various groups of mobile protection, check whether the wiring of the meter is correct, and overhaul the line equipment.

It is suitable for electric power, petrochemical, metallurgy, railways, meteorology, industrial and mining enterprises, scientific research institutions, metrology departments, etc.

Double Clamp Digital Phase Voltmeter adopts a large LCD display screen with white screen backlight, and the display is clear at a glance.

The instrument adopts an insulated non-slip sheath, has a data retention function, automatic shutdown function, simple operation, reliable and durable.

Feature:

1. Input by voltage transformer and current clamp, there is no high voltage in the machine, and the two inputs are completely isolated, which is safe and reliable.

2. The pointed and small jaws are suitable for places with dense wiring.

3. The test line adopts a special power cable, and the elastic rod plug and alligator clip are insulated and protected.

4. The use of large LCD display, white screen backlight, the display is clear at a glance.

5. High precision, high stability, low power consumption, and easy operation.
