3 digit red led Customers Reviews

  • Nice small voltmeter

    posted by GBDealX

    Small overall with bright clear display.Simple hookup with third wire allowing for monitoring voltage independent of meter power supply.
    Should come with some connection information although the connections for this unit are more intuitive than for the matching ammeter.Caution when connecting to measure voltage other than the meter power supply: the measured voltage source must either be complete isolated from the meter power supply OR share a common ground.
    Good display for permanent installation. Will not replace your multi-meter,
  • Great voltage meter

    CheapNice displayRelatively accurateLow power consumptionStandard socket dimensions
    Integrates nicely in my car interior, I used two; one for a household battery, one for the regular car battery. Quickly shows the change in voltage when the dynamo kicks in.
    Very good price / quality ratio, I'm going to reorder very soon for other projects.
  • Nice circuit pack

    Big bright indication, buzzer, big buttons, powerfull relay,very easy to install into the housing. Easy to use.
    It is nice universal device,accuracy is good.
    Maybe is is good to make tree different models - only heaters, only coolers and universal models.

    Easy to mount into panels..works prefectly.Operate: 2.45 - 30.5 VLights look great.So easy to place. Red line to the positive out and black line to the negative out.No screws, only pushing.Its bigger than I imagined. Very good for my panel.
    Used in power supply. Great for projects!!2.50 to 2.40 you can see the leds but without bright.
    Good Product, recomended to anybody who are looking some of this kind of products. Others are smaller and same price.

    Simple Voltmeter. Good case. Ideal for adding voltage measurement at home installations in a very inexpensive way. Quite accurate compared to UNI-T UT33C tester. Display has good visibility, day or night. Easily connects to your power supply and operates from the beginning.
    REALLY easy-to-use: just connect the wires and you get the voltage. Measure the alternating voltage from 0 to 600V
    A good product for constant monitoring of voltage. I recommend buying this Voltmeter. Will work as expected.
