Measure gas molecular weight
1. Acclimate DigiLEAK to surrounding
temperature for one minute, away from
measurement location.
2. Press for 1/2 second and then release the
front button. Display will come on
displaying 29.0 – molecular weight of
clean air.
3. With inlet close to target gas, repeatedly
press for 1/2 second and then release the
front button. Internal pump will activate
and surrounding gas will enter the sensor.
Observe the displayed molecular weight.
Find Subsurface water / Fuel pipe leak
Caution:
Thorough
pressurized gases is mandatory. Tightly adhere
to gas manufacturer directions.
 Close the main / street valve & Empty the
pipe.
 Apply Helium, Argon, or CO
close as possible to the leak.
 Increase gas pressure up to 15psi (105
KPa).
 Protruding the pavement, drill 6" deep, 1
foot apart holes in the ground.
 With gas pressure applied, wait for 10 to
30 minutes to allow sufficient amount of
gas to leak through defective segment of
the pipe.
Acclimate DigiLEAK to surrounding
temperature for one minute, away from
the location of the leak.
 Press for 1/2 second and then release the
front button. Internal pump will inject clean
air into the sensor. Display will turn on
displaying 29.0 – molecular weight of
clean air.
 With inlet positioned, within drilled holes,
repeatedly press for 1/2 second and then
release the front red button. Internal pump
will inject ground holes' air / gas into the
sensor. Observe the displayed molecular
weight. Molecular weight of Argon is 40;
Molecular weight of CO
weight of Helium is 4, molecular weight of
air is 29. Upon approaching the leak,
displayed molecular weight of air will
change as follows:
Increase, if Argon or CO2 is used
Decrease, if Helium is used
 Front Leak detect / proximity LED will turn
orange and then red.

1.
Determine if target gas molecular weight is lighter
or heavier than 29.0 – molecular weight of air.
2.
Acclimate DigiLEAK to surrounding temperature for
one minute, away from the location of the leak.
3.
Press for 1/2 second and then release the front
button. Display will come on displaying 29.0 –
molecular weight of clean air.
4. With inlet open repeatedly press for 1/2 second and
then release the front button. Internal pump will
activate and surrounding air will enter the sensor.
Observe the molecular weight displayed. As you
approach the desired target gas location, where
target gas is mixing with air, 29.0 molecular weight of
air, subject to target gas molecular weight, will
change to a different value. Leak Detect LED will turn
orange then Red indicating target gas close
proximity.
Find Vacuum mold leaks:
I. Setup:
Vacuum pump active.
Next to suspected leaks and gaps apply Helium,
Argon, or CO2.
Find a leak: Using DigiLEAK probe vacuum pump
exhaust. As gas leaks through the leak, molecular
weight of air – 29.0, will change. Also, led color will
change from green to orange and then to red.
II. Setup:
Attach a valve gas outlet to the mold.
With outlet valve open, replace all air by blowing
Helium, Argon, or CO2 into the vacuum inlet port of
the mold. Slightly increase pressure by gradually
closing the outlet valve.
Find a leak: Using DigiLEAK, probe for leaks around the
mold. At the place of a leak, molecular weight of air –
29.0 will change. Also, led color will change from green
to orange and then to red
