Section 2. Operation
2.1. Overview
The H-10 Pro sensor uses positive ion
emission technology, commonly known
as a heated diode. It is very sensitive to
only halon substances (refrigerants)
making this product highly resistive to
false alarming, while retaining superior
sensitivity for pinpointing the most
difficult to find refrigerant leaks.
A pump inside the unit draws air through
the probe to the sensor. The presence of
refrigerant(s) causes the H-10 Pro to
sound a speaker and illuminate an LED in
the probe. Sensitivity to pinpoint small,
medium, and large leaks can be
controlled by setting the Leak Size switch
(see Section 2.2).
