Dual-display: it can display auto battery voltage and temperature (Fahrenheit) inside the car simultaneously
External temp sensor: its external temp sensor allows you to bend sensor to avoid possible heating/ direct sunshine so that you can acquire more accurate results.
Safe usage: the monitor has built-in fuse, making safe usage possible and causing no damage to your car.
Easy reading: it is made of LED screen material, hence it is easy and convenient for you to read even in dim light.
Input voltage: 12V/ 24V
Power mode: cigarette lighter power
Display color: Red+Blue; Red+Green
(1) Auto battery voltage monitor
Firstly, plug the gauge into car cigarette lighter socket and its screen will display voltage of auto battery.
Secondly, the volt/temp gauge could be used in 12V car or 24V truck/ motor coach.
(2)Temperature tester inside your cars
Firstly, its testing range should be within 10-170 ℉.
Secondly, to gain accurate temperature, the temp sensor is set outside of the temp gauge. You can bend the sensor to avoid heating parts of car in your usage.For example, you can bend the sensor to avoid direct sunshine.
