Specifications: Material:ABS Type A:blue+red; B:green+red; C:red+red Measurement range :12 (V) Input voltage :12 (V) Output voltage :12 (V) Ambient temperature :45 () Voltmeter: Voltage meter temperature USB Size(about):Dia:4.3cm/1.7inch; length:8cm/3.1inch Description of 3IN1 3-in-1 voltage: Insert the baby into the car cigarette lighter jack, the screen will show the car battery voltage. (2) can be used for 12V cars, suvs, can also be used for 24V trucks, buses. (3) The significance of different voltages can be referred to the figure above. But because of the different models of battery, generator, stabilizer, different voltage meaning is not the same. This baby only tries to faithfully reflect the car battery voltage. Description of 3IN1 3-in-1 Thermometer: It can measure the temperature of -10~80 in the car. (2) In order to accurately measure the temperature, the temperature sensor is external to the product, the sensor can be bent when used to avoid the hot parts of the car that may affect the measurement results (such as the parts of the sun).
