  • Does the job

    Works well and are accurate.Easy to make attach into your dashboardVery simple to connect into your car or whateverproject you are using.
    A good value item
    I use two of those in our off-road car. One for the 24v system and one for the 12v system.They are accurate and the 24v shows the 12v x2 which is correct since there are two 12v batteries connected to each other. Measured it and found that it was accurate down to 0,1 volt. which is enough for most people.
  • Excelent purchase. The precision is very good.

    Very good precision.It is a good choice to have it installed to monitor specific power rails in more elaborate projects.
    I miss a way to change the decimal point. If it had one, it wold be interesting to use this module to monitor higher voltages using resistance voltage-divider or even other parameters whose range isn't in the [0,100] range. For example, a pair fo resistors plus a diode and capacitor wold enable using this module to monitor the 127/220V power grid lines. In those cases, the dot mark in the wrong place is annoying.
    Very handy to monitor volates, but it wold be even more usefull if we coold handle the dot mark. Other than that, it is excelent.
  • nice display

    I like this thing a lot, i had another one in red without the frame and it didn't look as good as this one, the blue color is nice and even, no dark sports, and seems fairly correct to me. The black surrounding around the display is made of the same material as most dashboards so could be integrated very wel in a dashboard without noticing. The display has a matte cover over it to enhance visibility in the sun or bright daylight.
    This is the way to go is you want a nicely finished display with a case to match so you can build it in in something

    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.
  • Nice small voltmeter

    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,
