Blue 200V digital voltmeter+pwr regulator smallest size

Blue 200V Digital Voltmeter+Pwr Regulator !Smallest!
3 Digit Blue LED DC Voltmeter Panel
Add-on regulator for 6-15V enabling power up.
Additional resistors for DIY modifications.
*This is the !!SMALLEST!! 3 digits panel DC Voltmeter.
*Made of super bright Blue LED tubes, High Quality!(Green LED also available)
Can also be altered by soldering couple resistors to full range:-19.9 to 20.0v -1.99 to 2.00v
*Display to the 1 digit after decimal, DC -199v to 200v.
*Comes with a 8 inch pigtail connection wire.
*It has filtering function that allows increase stability, but readout will slow down a bit. This function can be used when the readout keeps jumping up and down around the actual potential point.
*You can hold to readout by connection a switch to the "hold" position in the back. This function is used to when recording the readouts.
*It can be use in many places.Monitor you electronics behavior.
*Display certain parameter variation at fine resolution.
*Or simply monitor your RV or boat battery.
