- This voltage monitor has small size, adopting inported singlechip design which has software filtering function so the digits will not shake.
- This product uses fully automatic SMD technology which has good performance; the digital tube is displayed with high brightness so the digits will be clearly visible.
- The voltmeter is provided with two-level voltage regulation chip and has 3 wires to connect; 3 wires connection make the meter have stable power supply, high-brightness digital tube and no heating.
- With anti reverse polarity protection, so it will not burn when connected reversely; when it exceeds the measuring range, it wll display 0.
- It is suitable for monitoring the voltage of vehicle, car battery, and motorcycle battery; easy to install.
