4pcs 0.28 Inch Mini Digital Voltmeter Panel DC 2.5V-30V Two-Wire Voltage Tester Meter LED Display (4 Colors)

Function
The voltmeter can be used to measure the voltage of 18650 batteries, mobile lithium batteries, nickel metal hydride batteries and other battery packs as well as the voltage of motorcycles, cars and other batteries, and can also be used for other voltage measuring purposes.

Specification:
Operating voltage: DC2.4 ~ 40 V.
Detection voltage: DC2.4 ~ 30 V.
Working current: <30 mA.
Display: 0.28 inch LED.
Measurement rate: ≥200 mS/times.
Measuring accuracy: 3‰ (+/- 1 word)
Working temperature: -10 ~ +65 ℃.
Operating humidity: 10 ~ 80%.
Working pressure: 80 ~ 106 kPa.

Attention:
1. Caution, the input voltage must not exceed 40 V, otherwise there is a risk of combustion.
2. When the voltage is lower than 3.0V, the brightness of the display is dampened, but does not affect the correct measurement.

Package includes:
4 x mini digital voltmeter (red, yellow, green, blue)

The voltmeter can be used to measure the voltage of 18650 batteries, mobile lithium batteries, nickel metal hydride batteries and other battery packs as well as the voltage of motorcycles, cars and other batteries, and can also be used for other voltage measurement purposes.
This package contains 4 colours mini digital DC voltmeter: red (2.5 V – 30 V), yellow (2.6 V – 30 V), green (2.6 V – 30 V), blue (3.2 V – 30 V)
Equipped with two wires, convenient and easy wire connection, easy to connect to the car, battery car, motorcycle car line
With reverse polarity protection, the wire will not be burned when the connection is reversed.
The resolution is 0.01V when the voltage is measured below 10V, resolution is 0.1V for voltage above 10V. This can ensure the accuracy of the measurement, but also the need to measure higher voltages.
