12V / 24V Voltmeter built-in gauge
Our super compact built-in voltmeter monitors the battery in your camper, boat or motorcycle. When measuring, it supplies itself with power, so that you don't have to install any additional cables.
The voltmeter works in a voltage range between 2.5 and 30V.
Dust and waterproof according to the IP67 standard and therefore also ideally suited for the use on boat or motorcygle.
The three digits LED display has a floating decimal point for better Resolution below 10V (i.e. for the readability of two decimal places, at a voltage of less than 10V).
Please take care of charging your battery BEFORE this. This voltmeter is designed to help you do just that - so that you don't accidentally have to buy a new, expensive battery soon. With a display that is easy to see at all times, you always have an eye on the voltage.
