Instrument Description
The GasCheck Tesla is a portable, handheld gas leak detector capable of detecting helium leaks within a high magnetic
field, typically surrounding Magnetic Resonance Imaging (MRI) scanners and can be effectively used while the
machinery is still in operation. GasCheck Tesla is part of a range of gas leak detectors 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 Tesla uses thermal conductivity to detect gas which offers a robust sensor technology that
requires practically no maintenance beyond annual servicing.
All GasCheck models have an easy to use graphical interface with an intuitive keypad allowing simple function
selection and adjustment. The instrument has an LCD display, LED indicator and audible sounder that indicate the
detected signal.
Applications where GasCheck instruments are typically used include:
•
Medical - used by service technicians during maintenance of Magnetic Resonance Imaging (MRI) scanners and
testing of membrane materials and sealing of glove boxes.
•
Laboratory applications - detection of leaks from mass spectrometers and chromatograph equipment.
•
Quality assurance - testing seal integrity after product manufacture.
•
Industrial - leaks from gas cylinders, pipe work and process equipment.
•
Pneumatic - valve seal testing.
The GasCheck Tesla 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.
Selectable units:
cc/sec
Cubic Centimeters per second offers a reading that indicates the volume of gas escaping into
atmosphere from a single point i.e. leakage from a hole in a gas filled vessel or pipe.
ppm
Parts Per Million is a concentration reading. GasCheck Tesla will display the concentration being
detected however it is more difficult to gauge the quantity of leakage.
mg/m
3
Milligrams per meter cubed is also a unit that measures concentration. (See ppm above)
g/yr
Grams per Year is an alternative measure of leak rate.
NOTES:
GasCheck Tesla is NOT intrinsically safe so should not be using in a potentially explosive environment. Please contact

Ambient air pressure, heat and humidity can affect readings.
The GasCheck Tesla range is NOT 'Gas Specific' i.e. it can NOT differentiate between gases. Selecting a specific gas on
the GasCheck Tesla allows the instrument to calculate concentrations and leak rates of that gas only if that gas is being
detected.
