Ψηφιακό βολτόμετρο για μέτρηση τάσης 4.5V-30V DC μπορεί να τοποθετηθεί σε πίνακα και να ελέγξετε την τάση του δικτύου.

Τάση λειτουργίας: 4.5V-30V V DC 

Ενδείξεις: Ψηφιακές (LCD οθόνη 3 ψηφίων) της τάσης (Volt)

Διαστάσεις: 48x30mm

Features:

1. The wire connection is simple, only need to connect two wires, the red line connect the anode, the black line connect the cathode. Inside the voltmeter, there are reverse polarity connect protection.

2. This voltmeter work without external power supply, can use the measuring voltage directly, Wide working voltage range of 4.5-30V

3. For best accuracy of measurement, depending on the measuring voltage, the voltmeter automatically move the position of the decimal point. when voltage is below 10V, it shows two decimal places; when voltage is over 10V, it shows one decimal place.

4. The voltmeter can be used in motorcycles, cars etc monitoring battery voltage, grasps the battery state timely. can also be used for other voltage measurement purposes
