Leak detectors are essential tools for maintaining and repairing vehicle air conditioning systems, helping technicians to quickly and accurately identify potential refrigerant leaks. These devices can use a variety of technologies, such as UV light, ultrasound or special sensors to detect the presence of refrigerant in unwanted areas of the system. Leak detection components may include sensor heads, batteries, filters, and display panels. Regular maintenance and timely replacement of leak detector components is essential to maintain the reliability and accuracy of the unit, ensuring effective diagnosis and repair of the air conditioning system.
