Material:High quality plastic Size:length：48mm,Width：29mm,Height：22mm Nominal voltage:0-30V Color:Red Package Include:1 pieces mini digital voltmeter These mini digital voltmeters can help you to indicate charge remaining and to monitor voltage.The display is pleasant to work with and it's default accuracy against multimeter readings almost exactly.
Product Features
- Monitor easily:Tired of holding a voltmeter while you are checking battery voltage?Install one of these on the battery to indicate charge remaining and another one on a prototype setup to monitor voltage,now it only take one glance to understand the state of power supply.
- Bright light:They have powerful light shining on the front panel.Lights are so bright and vivid that allows you to put colored electrical tape over them to modify the light depending on the application.The display is pleasant to work with and large enough to read from several feet away.
- Simple install:They're small so they take up only very little room to install.Just connect 2 wires and use it,no other preparation needed.It is very easy to add on a breadboard set of pins with a little soldering,or install it with double sided tape or plastic screws/standoffs.
- Default accuracy:Low current draw,they doesn't affect the circuit balance at all.Its default accuracy against multimeter readings almost exactly,tracks pretty good over the stated range.You can also calibrate for better accuracy as needed,look for the tiny cross-point adjustment on the back.
- High compatibility:From RC toys to your ham radio,these accurate little meters are easy to read and wire up.Using them to point-test during prototyping or monitor power supplies,auto battery voltages and charging systems,they will work fine.Also helpful for your micro-controller and solar powered projects.
