## Overview

The Digital AC Voltage Frequency Meter is a compact, high-precision tool designed for real-time monitoring of AC voltage (80-500V) and frequency (45-65Hz). Featuring a bright dual-color LED display and rapid 2 readings per second update rate, it’s perfect for generators, RVs, and motors. Its simple 2-wire installation and low power consumption make it an essential, hassle-free safeguard for your valuable electronics.

## Description

This AC voltage frequency meter can atuo detect the real time voltage and frequency. Perfect meter to monitor RV or home generator and shore power. Just what you need to add-on for your generator. It's a good reminder. Wide working voltage range, AC 80-500V Frequency measuring range 45-65Hz Two wires design Easy to use, connect two wires directly, the meter can automatically detect the accurate real-time voltage and frequency " Clear and bright LED digital display, much better than LCD Low power consumption Small size and portable, very convenient Widely used in different modes of gasoline engine generator, diesel engine generator, motor and RV Technical Parameters: Working voltage: AC 80-500 V Working frequency: 45-65 Hz Measurement speed: 2 times/s Measuring Accuracy : 1%±2 digits Operating Temperature: -10～+50℃ / 10℉~122℉ Operating Humidity: 10～80%(no condensation) Working Pressure: 80～106kPa Display: LED displayer(Red&Green) Material: ABS Product dimensions(WxDxH):2.75"x1.18"x1.57"/ 7x3x4cm Net weight:1.3oz/36g Usage tips: Application: This meter is only suitable for pure AC 45-65Hz power supply, can not be used for square wave, inverter output and modify the sine wave sine wave circuit measurement (it can't be used for measuring the AC power converted from a DC power with an inverter), otherwise the meter will damaged! Install method: you can dirrectly connect two wires to the tested voltage to measure voltage and frequency . Package includes: 1 x AC voltage frequency meter

Review: Accurate Easy To Read - After destroying my plasma cutter it was necessary to know the frequency & voltage of my portable generators. This meter instantly solved my problem. I tested it first on my oscilloscope and another known accurate meter and it was exact. Rather than modify my generators, I made a small mounting panel for it to attach to the frame. Then wired it directly to the back of one of the outlets. It's easy to read in bright sun and even looks good. Cheap insurance for valuable electronics and equipment. I wish I had the sense to buy & install this before I had a problem. Absolutely, I'd buy it again!
Review: Works good. Looks good. - Good looking unit. Very accurate. EZ install.
