used in the 753 and 755?
The Advanced Ionization Technology (AIT)
micro tip provides increased stability over a
standard corona discharge tip. This enables the
use of an internal pump to draw the sample
across the sensor, increasing overall sensitivity
and response of the 753 and 755 detectors.

The 753 and 755 both use AIT micro tips and
have pumps. Why is the 755 more sensitive?
The 753 uses a standard duty pump to pull the
sample at a medium rate across the sensor. The
755 uses a heavy duty diaphragm pump to pull
the sample at a fast rate across the sensor. The
difference in sample rate makes the 755 more
sensitive.
Should I buy a thumb wheel "tic" adjust or
push button "tic" adjust?
The thumb wheel gives you a manual
adjustment and the push button adjusts to
preset levels. Both are easy to use and work
equally well. It's simply a matter of personal
preference.
Why would I want a pump on my
refrigeration leak detector?
Generally, refrigeration leak detectors with
pumps respond and clear faster as you enter or
leave the leak area. This is most important
when locating small leaks.
I have a hard time finding a leak when on a
rooftop in windy conditions. Will I be able to
find a leak in the conditions with your
refrigerant leak detector?
Always remember that the refrigerant will travel
with the wind. Position yourself down wind
and work your way "up stream" in order to trace
down a leak. The harder the wind is blowing,
the more the concentration of refrigerant will
be diluted in the air. It is difficult to find these
leaks, but it can be done.
Is there a way to determine how many parts
per million (ppm) a leak of 0.1 ounce per year
(oz/yr) is?
A leak of 134a refrigerant measuring 0.1 oz/yr is
equivalent to approximately 380 to 400ppm. A
leak measuring 0.2oz/yr is equivalent to
approximately 760 to 800ppm.
Can any TPI refrigerant leak detectors to be
used to test for SF6?
Sulfer hexafluoride (SF6) is used in high voltage
insulation as found in high voltage lines and
circuit breakers. SF6 is toxic and emitted into
the air when high voltage insulation begins to
degrade. The 755 will detect SF6 at a level of
750ppm or higher.
Is there anything I can do to extend the life of
the sensor?
Even though the sensors are very durable, you
can extend the sensor life of your leak detector
by press fitting a ?" long piece of vinyl tubing
onto the sensor tip. This will help prevent

foreign material from getting into the sensor
during tests. Clean or replace the tube regularly.
