Answer :
The correct answer is c. soap bubble leak detectors. Soap bubble leak detectors are a universal tool for detecting leaks in all high pressure refrigerants, as they provide a visual indication of a leak through the formation of bubbles.
Soap bubble leak detectors can be used for leak detection with all high pressure refrigerants. This method is simple and cost-effective, requiring the application of a soapy solution to suspected leak sites on refrigeration systems. When leak points are present, bubbles will form due to escaping refrigerant gas.
This is a visual confirmation of a leak. While other detectors such as electronic, ultrasonic, and infrared may provide more sensitivity or allow for automation, soap bubble leak detectors are a universal tool that can be applied across different types of refrigerants regardless of their pressure or chemical composition.Therefore, the correct answer is c. soap bubble leak detectors.
