DC0V-100V Digital Battery Voltmeter 0.28 Inch Ultra Small Size

Description:

This voltmeter is small in size, with a range of DC0-100V DC, and is common for 2-wire and 3-wire products. It breaks the conventional voltmeter and is the latest design. It can directly work in 5V, 9V, 12V, 24V and other circuits without voltage regulation. Equipped with three wires, it is convenient to connect to the car/battery car/motorcycle internal circuit, with reverse connection protection function, the wire connection will not burn. It is used to monitor the battery voltage and grasp the battery voltage status in time. It can also be used for voltage measurement of other products. Note that the maximum input voltage used for the 2-wire cannot exceed 30V, otherwise there is a danger of burning.

Note: The voltage range of three-wire use is 0-100V, and it can also be used as two-wire but the voltage should be within 40V
