- 100% Brand new and high quality
Adopt whole sealing shell, potting waterproof design, moisture resistant, oil resistance, and anti-vibration
Apply 0.56" LED nixie tube for display parts
Easy installation, just connect the two wires, built-in reverse protection, which means it will not burn if you connect the wires reversely
Low starting voltage (2.5V for red LED display, 2.7V for green LED display, 3.0V for blue LED display) to ensure accurate measuring, which is the lowest starting voltage in the world compared with those voltmeters with competitive price
Great convenience for users who apply lithium battery or 18650 battery
Display brightness will turn dark when the voltage is lower than 3.5V, while it won't affect accurate measuring.
For best accuracy, the voltmeter will automatically move the position of the decimal point according to the difference of measuring voltage: It will show two digits behind the decimal point when measuring voltage is below 10V, and show one digit behind the decimal point when measuring voltage is above 10V.
It can be applied to motorcycles and cars to monitor the battery voltage and control battery status in time and also be used for other voltage measurement purposes.
