Instrument description
Panther is predominantly used for detecting gas leaks and can detect almost all gases to varying degrees.
Panther uses thermal conductivity as it's means of detecting gas, which offers a robust sensor technology that
requires practically no maintenance beyond annual servicing.
Both Panther & Panther PRO have an easy-to-use graphical interface with an intuitive keypad allowing simple
functionality selection and adjustment.
Panther has a coloured LCD display, LED indicator and audible sounder that indicates the detected signal.
Common applications where Panther is used:
• 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
Panther is calibrated against a 5 E-4 cc/s Helium leak to allow volumetric readings and 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. ie. leakage from a hole in a gas filled vessel or pipe.
ppm Parts Per Million is a concentration reading, Panther 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.
%Vol This is a measure of the percentage of the target gas in the environment.
