1/2/5pcs Two-Wire Voltage Tester, 2.5V-30V Mini Digital DC Voltmeter with 0.28 Inch LED Display Display Voltage Tester DC Meter

Operating Voltage: DC 2.4~30V (with reverse connection protection function, when the voltage is lower than 3.0V, the display brightness will be dark, but it will not affect the correct measurement. Note that the input voltage cannot exceed 40V, otherwise there is a danger of burning)

Detection voltage: DC2.4~30V Working current:<30mA Display mode: 0.28LED Measuring rate: ≥200mS/time Measurement accuracy: 3‰ Able to adjustable voltage resistance - Turn clockwise to lower voltage, it can work directly in 5v, 9v, 12v, 24v Working temperature: 14℉～149℉(-10～+65℃) Working humidity: 10～80%RH (No condensation) Working pressure: 80～106kPa Sun exposure: no direct exposure

Measuring accuracy: This voltmeter will automatically move the decimal point position according to the different measuring voltage. When measuring voltage below 10V, two decimal places are displayed; When measuring a voltage greater than 10V, display one digit after the decimal point.

Range of use: This voltmeter can be used to measure the voltage of 18650 batteries, mobile phone lithium batteries, nickel-hydrogen battery packs and other battery packs, as well as the voltage of motorcycles, automobiles and other batteries. It can also be used for other voltage measurement purposes.

Color: The package includes 5 colors of Mini Digital DC Voltmeter: Red: 2.5V-30V Yellow: 2.6V-30V Green: 2.6V-30V Blue: 3.2V-30V White: 3.0V-30V package ：1x mini voltage teste Or 3 x mini voltage teste Or 5x mini voltage teste
