2 RLD-H10G Product/Technical Bulletin
A
pplication Overview
Growing concern over the effects of certain
refrigerants on the atmosphere has generated a strong
motive to eliminate system leaks and to develop safer
refrigerants. With the RLD-H10G, you can be
confident that your instrument will provide the
sensitivity and capabilities to meet your service needs
today and for the years to come.
The RLD-H10G is intended principally as a service
technician’s tool. This detector has the capability to
detect small amounts of halogenated gases, including
chlorine and fluorine based refrigerants and blends.
T
heory of Operation
The leak detector consists of a control unit with a
manual balancing circuit, a probe with a 4.5 ft cable,
and a 6 ft power cord. The sensor uses positive ion
emission technology, which is based on the ionization
characteristics of alkali metals. The alkali metals act
as the cathode of a diode, and the anode is heated by
a DC voltage. Air from the area being leak checked is
pumped from the probe and into the space between
the cathode and anode. If halogen gas is present, it
creates an ionized current between the cathode and
the anode, which is amplified to sound a speaker and
light a neon lamp in the probe. Sensitivity can be
controlled by adjusting the current (temperature)
through the sensor.
