Question

the type of refrigerant leak detector that uses an internal pump to pull in vapor samples is the ______ leak detector.
○ halide
○ electronic
○ ultraviolet
○ ultrasonic

Explanation:

Electronic leak detectors for refrigerants often use an internal pump to draw in vapor samples for detection. Halide detectors use a flame - related mechanism, ultraviolet detectors rely on UV - related detection of refrigerant (not typically with an internal pump for vapor sampling), and ultrasonic detectors detect sound - related leaks. So the electronic leak detector is the one with an internal pump to pull in vapor samples.

Answer:

electronic
