Product Highlights
- Has very stable output, input range is dc 4~40v and output range is dc 1.25~37v, please make sure the input voltage should be higher than output voltage at least 1v. can be used for many electronic projects.
- With input and output voltage measurement error calibration function; wiring terminals require no soldering iron and create convenient usage.
- Analog control: using a mini screwdriver to increase or decrease output voltage by adjusting the screw, clockwise to step up voltage and counterclockwise to step down voltage.
- Press the button next to voltmeter to test input voltage or output voltage. green led lights on when testing output voltage; red led lights on when testing input voltage.
- Press the button for 1 to 4 seconds, voltmeter would be shut off when releasing your hands; the voltmeter is very accurate.

Product Highlights
- External temp sensor: the car thermometer with external temp sensor allows you to bend sensor to avoid possible heating/ direct sunshine so that you can acquire more accurate results.
- Easy reading: its screen is made of led material, hence it is easy and convenient for you to read even in dim light.
- Dual display: it can display auto battery voltage and temperature inside the car simultaneously(this is for fahrenheit); input voltage is 12v or 24v, temperature testing range is 10-170 ℉.
- Safe usage: the volt temp monitor meter has built-in fuse, making safe usage possible and causing no damage to your car.
- Power mode: the car thermometer inside power mode is cigarette lighter power.
