  • Easy to use instrument

    posted by Markymarker

    Easy to connect, read and understand. Seems to be accurate as well: Compared to readings from Fluke's multimeter. Casing is small and can be mounted easily. Quality of electronics look ok and may last for a long time before anything breaks.
    Since I do not know enough about the inner workings of this instrument, I am worried how much it consumes battery life when connected.
    Easy product that I would recommend to anyone - but with caution.
  • Great Voltmeter!

    Small boardVery good solder -high quality surface mounted, I was amazed really!Useful range (4.5 - 30V is more than I will ever use)No additional power source needed.Low power consumption.There is a trimpot, and you can calibrate it when needed.PCB is very small, but you have two mounting holes on edges!
    You can use it in in many many DIY projects, will fit anywhere!I am going to fix it to home emergency power supply unit.
    I recommend buying this Voltmeter.Will work as expected.
  • simple to use digital voltmeter

    Compact size, no backlight required because of LEDs display, just two wires to connect (powered by the same battery you measure). Wide range of input voltage.
    The power circuit has a protection against the reversed voltage (a diode in series of an IC voltage regulator) which is good but increases the lowest voltage you could measure.
    It's a great companion to battery chargers where you don't see any voltage information. Good module for DIY projects. The price could be lower because you can buy some simple multimeter for the same money.
  • Nice small meter

    Small overall size with bright, clear 3 digit display.Includes connectors and short leads along with a built in shunt.
    This same unit is available from other mainland suppliers at lower prices.
    It works and provides an inexpensive approximation of current which is good enough for many applications. It will not replace a good multi-meter.
  • Precious instrument

    It is a highly appreciated element to take the pulse to the load of a car. It is a small device that can be placed anywhere in the cabin, its construction is of quality.It has a beautiful blue screen that indicates the amperage reading accuratelyResistance shunt which has the device is large and looks very robust to be able to install without problems in the engine compartment without fearing that it can deteriorate with temperature or with a sharp blow.
    Beautiful and useful automobile generator current meter.
    Excellent value for money
