Dual Display Voltmeter LED Detector Digital AC Monitor Gauge Panel Ammeter Generator Transformer for

[PRODUCT SPECIFICATION]:This capacitance and watt meter can display the AC voltage and frequency of 80-500V LED at the same time. Display Mode: 0.39in LED, voltage: red word, frequency: green word. Measurement Accuracy: 1%( +\/- 2 words ). Testing Rate: 2 times\/sec . Frequency Measuring Range: 45.0 - 60.0Hz Minimum Resolution: 0.1hz.[PRODUCT DESCRIPTION]:The digital AC voltmeter and frequency meter simultaneously display the measured AC voltage and AC current on the same instrument. The enclosure of the instrument is fully enclosed and designed to and reliable.[FEATURE]:The data is more intuitive, LED two-color display, red + green, clear and easy for monitoring at a glance. It do not need power supply, two wires just connect with AC 80-500V directly, then you can finish testing.[WIDE APPLICATION]:This current sense transformer only fits with pure AC 45-60HZ power supply, not be used for square wave, inverter output.[PRODUCT ADVANTAGE]:This voltmeter ammeter has handy connection and wide application, for example, it can be applied to monitoring storage battery, DC adjustable power supply, or voltage and current changing state of other device.Colour: blackMaterial: ABSSize: 7x4x3cmPackage Contents:1 * Dual Display VoltmeterOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +\/- 1-3cm.
