  • Great voltage meter

    posted by messersDX

    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.
  • Useful device

    posted by k3bab

    Displays voltage for each cell, then for all cells together.
    Lightweight, so you can leave it in your car while driving. Useful when you're in a race. Just drive the car into the pit-stop and check the display without having to take the cars shell of and connect the display.
    It displays like this in a loop:
    no1
    3.72
    no2
    3.69
    no3
    3.70
    etc....
    ALL
    11.1
    Recommended. Get one of these if you have a LiPo battery.
  • Easy to use volt / amper panel

    posted by alikox1

    This panel meter has a small size that make it ideal for small projects. Different colors for volt and ampere readings makes it easy to read. Decimal point is adjusted automatically based on the value read.On the back side, there are two separate small calibration points for voltage and ampere readings. Use them first to calibrate against a well known multimeter.
    Ampermeter is based on the voltage reading on a small shunt resistor, it does not contain a Hall effect sensor as with the more advanced ammeters.
    Great value for money. I bought one for my DIY PSU project.
  • good clock

    posted by bujdos

    Good brightness of display, adjustable in 3 steps.Clock back-up by internal battery, quite accurate (error ~1 sec per week).Simple control.
    Thermometer reasonably accurate, resolution 1°C. Resolution of 0.1°C would be nice (although the practical usefulness of such resolution is questionable).When supply voltage is less then ca. 10V, the reading of the voltmeter is wrong (although the gadget works from 5-6V). At 13.5 V it draws 40-50 mA.
    The display has a bit "dense" look, the numerals are close to each other.
  • LED meter

    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.
