LACO USER MANUAL - GASCHECK G SERIES
This manual contains safety, operation, and maintenance information
for GasCheck G Series handheld snier leak detector. Our leak detectors
are designed to ensure safety when used properly. It is the responsibility
of the user to follow safety-related warnings, cautions, notes, and other
requirements described in this manual.
Should a question, comment or problem arise, the information below
is provided as a guide. When returning a unit for factory service or
calibration, contact Portable Leak Detectors for a return material
authorization number (RMA). The device should be boxed securely and
contain all contact information, including return shipping information.
If the device is being sent to the factory for service, a written statement
of the problem or symptoms should then be included. The RMA number
must be on the outside of the package or indicated on the shipping label.
Please read this manual in full before using the GasCheck G Series
instrument. Portable Leak Detectors takes no responsibility for damage,
injury or death resulting from misuse, misunderstanding or negligence
while using this gas detector. Please contact Portable Leak Detectors for
clarication on any aspect of this manual that is not understood or for
additional information.
2.1 QUALITY ASSURANCE
GasCheck G Series instruments are manufactured in compliance with
ISO9001:2000, which ensures that the equipment supplied to the customer
has been designed and assembled from traceable components, leaving
Portable Leak Detectors calibrated to traceable standards.
2.2 RESPONSIBILITY OF USE
Many gases are hazardous and can cause explosion, poisoning and
corrosion resulting in damage to property and life. It is the responsibility
of the person using this instrument to ensure it is being used in
accordance with this manual and that the instrument is functioning
correctly before use.
The GasCheck G Series handheld leak detectors can detect a large range
of gases but some gases are more dicult to detect. It is the responsibility
of the user to ensure the GasCheck instrument has the sensitivity to detect
the required gas before reaching potentially dangerous levels.

LACO USER MANUAL - GASCHECK G SERIES
2.3 DISPOSAL
Disposal of the GasCheck G Series its, components, and any used batteries
shall be in accordance with local and national safety and environmental
requirements.
2.4 CALIBRATION
Calibration service is recommended on a yearly basis. LACO Technologies
has an A2LA Accredited calibration lab which complies to ISO/IEC 170252005 and ANSI/NCSL Z540-1-1994. Also complies with ISO-9001 quality
standard. Call LACO at 801-486-1004 for more information.
The GasCheck is a portable handheld gas detector instrument
predominantly used for detecting gas leaks and can detect almost all
gases to varying degrees. It is powered by standard AA size batteries and
will accept both Alkaline and Nickel Metal Hydride (rechargeable) types.
The GasCheck uses thermal conductivity as its means of detecting gas
which oers a robust sensor technology that requires practically no
maintenance beyond annual servicing.
All GasCheck G Series models have an easy to use graphical interface with an
intuitive keypad allowing simple function selection and adjustment. It can
be upgraded to add features without the need to be returned to the supplier
and without having to modify the internal rmware. It has an LCD display,
LED indicator and audible sounder than indicates the detected signal.

3.1 APPLICATIONS
Common applications include:
• Quality assurance: Testing seal integrity after product manufacture
• Laboratory applications: Detection of leaks from mass spectrometers
and chromatograph equipment
• Industrial: Leaks from gas cylinders, pipe work and process equipment
• Medical: Testing of membrane materials and sealing of glove boxes
• Pneumatic: Valve seal testing.
3.2 UNITS OF MEASUREMENT
The GasCheck is calibrated against a 5 E-4/cc/s helium leak to allow
volumetric readings and also a 5000ppm helium to allow measurement of
concentrations.
Table 3: Selectable Units of Measurement
UNIT DESCRIPTION
cc/sec Cubic Centimeters per Second oers a reading that indicates
the volume of gas escaping into atmosphere from a single
point, i.e., leakage from a hold in a gas lled vessel or pipe.
ppm Parts Per Million is a concentration reading. The GasCheck G
will display the concentration being detected. However, it is
more dicult to gauge the quantity of leakage.
mg/m3 Milligrams per meter cubed is also a unit that measures
concentration. (See ppm above)
g/yr Grams per Year is an alternative measure leak rate.

3.3 IMPORTANT NOTES
The GasCheck G Series range is NOT intrinsically safe, so it should not be
used in potentially explosive environment. Intrinsically safe GasCheck
instruments are available; please contact Portable Leak Detectors for more
information.
• Ambient air pressure, heat, and humidity can also aect readings.
• The GasCheck G range is NOT “gas specic”, i.e., it cannot dierentiate
between gases.
