Question 10Refrigeration & AC - QMED
70% to passWhich of the following leak detectors would be appropriate for use in leak detecting on a system currently pressurized with nitrogen? Illustration GS-RA-04
AA
BB
CC
DD
AI Explanation
The correct answer is D. The reason D is the correct answer is that a halogen leak detector, such as a halogen leak detector, would be the appropriate choice for detecting leaks in a system pressurized with nitrogen. Halogen leak detectors are designed to detect the presence of halogen-based refrigerants, which are not affected by the type of pressurizing gas used in the system. The other options, A, B, and C, would not be suitable for this application, as they are designed for different types of leak detection, such as soap bubble testing or electronic leak detectors, which may not be effective for nitrogen-pressurized systems.
