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.
Being a hand held instrument 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 as its means of
detecting 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 Centimetres 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.
IMPORTANT NOTES:
GasCheck Tesla is NOT intrinsically safe so should not be using in a potentially explosive environment. An
Intrinsically Safe leak detector is available (GasCheck IS). Please contact Ion Science Ltd for more

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.
