Visualization of polarity enables efficient work! The adoption of high-brightness LEDs makes it easy to see even outdoors.
Our company offers a "DC Power Polarity Checker" that helps prevent accidents caused by incorrect connections of DC power supplies by instantly confirming polarity through light color. It can safely confirm polarity for a wide range of devices, including -48V specifications such as rectifiers and batteries for communication equipment, as well as 12V to 24V specifications for trucks and passenger cars. Additionally, it features high-brightness LEDs that provide excellent visibility even during outdoor daytime work. 【Features】 ■ Long lifespan with high-brightness LEDs ■ The positive terminal lights up "red" and the negative terminal lights up "blue," even when the measuring rod is switched. *For more details, please refer to the related links or feel free to contact us.
