12V/24V DC Digital Red LED Panel Meter on/off Switch 30V Max No ext power needed

12V to 30V DC Digital Red LED Panel Meter

Auto-Brightness

With On/Off switch

 
Finally an affordable, ready to go volt meter for your alternate energy system. 
 

A highly-efficient yet flexible meter which can be used to measure the voltage of 12 or 24 volt battery banks directly.  No separate power supply is needed! Simply hook up the two lead wires directly to your batteries.  

This meter is also perfect for measuring vehicle, yacht, electric toy, tool or motorcycles having a single or double set of 12V storage batteries.

Advantage over other panel meters by competitors:

  • Compared with LCD panel meters, this LED panel meter has a high contrast, wide viewing angle with very easy to read numbering.
  • Super convenient operation (DOES NOT need an additional power supply.) Hook up the two leads and you are set.
  • Self adapted to ambient brightness, not dazzling in night time as the panel meter will automatically adjust its brightness.
  • On/Off Switch -- This meter uses only 13ma ( .0013 amps) in darkness. If you are like many of us who simply do not like wasted energy, regardless of how small it is, then you will love this meter, as you can simply shut if off when you are not using it.
  • Great looking, black matte solid metal face plate, mounts on a standard dual switch outlet box (included.) This allows you to flush mount it if desired into a standard electrical switch box.




The camera cannot do justice to the clarity of the display.
The LED characters are quite perfect.
The camera is simply unable to focus on this unit properly.

No manual is included with this meter, as it is about as simple as it gets, and we would rather not waste the paper.

To use this meter, simply hook up the red lead wire to your positive battery post (or energy source), and the black wire to the negative side. The meter will function great in the range of 8.5v to 30v. If you exceed 30 volts it will read "1___", voltages lower than 8.5v may be inaccurate.

Flip the switch up to turn the meter on, and down to shut if off. That's about it, super simple, yet super functional!
