Page 4: Statements
The 8067 can detect a large range of gases but some gases are more difficult to detect. It is the responsibility of the user to ensure the 8067 instrument has the sensitivity to detect the required gas before reaching potentially dangerous levels. -
Page 5: Instrument Description
All 8067 models have an easy to use graphical interface with an intuitive keypad allowing simple function selection and adjustment. The 8067 can be upgraded to add features without the need to be returned to the supplier and without having to modify the internal firmware. -

6 times faster. The 8067 contains a heated thermistor bead that transmits heat to a block of material that remains at a constant temperature. As air passes through the detector chamber a constant amount of heat passes from the bead to the block. -
Page 8: Instrument Main Menu
Instrument main menu Once the 8067 has run through its 'Start up' routine, it will display its normal 'Running screen' used when locating gas leaks. Before using the instrument the various settings should be set and adjusted to suit the application. - Page 9 The 8067 displays the gas being measured in the top left of the running screen. The 8067 will display the gas selected at the factory only, however the 8067 model has a range of gases that can be selected via an internal gas table.

'ENTER' key until the data is deleted. Press the 'Esc' key to exit to the Main menu. Units 8067 instruments have the capability of displaying detected readings in a variation of units; ppm, cc/s, mg/m and g/yr. -
Page 12: Gas Selection
Functions Gas selection 8067 is calibrated using Helium gas at time of manufacture, however other gases can be detected and measured using a gas table within the instrument. Although 8067 can't differentiate between gases it can quantify other gases using response factors stored in its internal gas table. -

Page 14: Using The 8067
Ensure the instrument is on the X100 (times one hundred) range, while on the main running screen use the UP and DOWN key to adjust between sensitivity ranges. X100 is most sensitive, X1 is the least sensitive. Gas leaks tend to occur at pneumatic joints or welded seams, hold the 8067 at a 45 angle to the object being tested and drag the probe along the seam or joint at a rate of approximately 25mm per second. -

WARNING: Ensure safety guidelines are adhered to when using compressed air. (MATHESON takes no responsibility for injury or damage caused by misuse of compressed air equipment) MINT-0313-XX Page 15 of 21... -
Page 16: Detecting Leaks
Avoid touching the brass sensor block with fingers. * The 8067 can detect changes in Humidity and Carbon dioxide, therefore avoid breathing on the probe. * The thin white tube that covers the inner probe should not be removed. This tube ensures a 1mm gap is maintained between the probe and the surface being tested. -
Page 17: Calibration
'tick / check' under the 'Custom Cal' symbol and press the ENTER key. The 8067 requires either 5000 ppm Helium concentration or a 0.0005cc/sec (5 E-4 cc/sec) leak rate as a reference. The 8067 automatically selects the type of Calibration media based on which units the instrument already has selected. -
Page 18: Calibration Procedure Using 'Cc/Sec' Units
ESC key to start using the instrument or press the ENTER key to recalibrate again. NOTE: * 8067 can detect changes in Humidity and Carbon dioxide, therefore avoid breathing on the probe. WARNING: Great care should be taken to ensure the calibration gas is neither pressurised or restricts flow to the instruments probe. -
Page 19: Instrument Warranty And Service
Standard Warranty is one year from date of purchase. Service At Matheson Tri-gas we recommend that all of our gas detection instruments be returned for service and factory calibration once every 12 months. Contact Matheson Tri-gas or your local distributor for service options in your area. -
