This dialog allows you to preset the gas type and the unit for the indicated
values (concentration or leak rate).
The current settings are always highlighted in light blue.
Gas types
• H2: 100% hydrogen
• 5% H2: 5% hydrogen in nitrogen
• ~R134a: equivalence leak rate for R134a while using trace gas
• ~R600a: equivalence leak rate for R600a while using trace gas
The leak rate calculated here is only a guideline. A precise
calculation is not possible because for a complete equivalence
analysis between trace gas and R134a/R600a. Leak-specific
parameters must be considered which vary for the leaks being
analyzed and in general are unknown in the field.
• R22, R134a, R290, R404A, R407C, R410A, R600a: Refrigerant
• C02: carbon dioxide
The preset gas type is indicated in the outputs of leak search modes.
Setting the gas type
List selection (press a list entry, scroll by pressing and simultaneously moving
the finger up and down or by pressing the scroll bar, the current setting is highlighted
in light blue)
Unit for concentration or leak rate
Concentrations are generally determined by the device (ppm) and are
then converted to leak rates. The critical unit is thus the concentration
data in ppm.
The other units, g/y (gram/year), oz/y (ounces/year), atm ccm/s (atmospheres
cubic centimeters/sec) or mbar l/s are calculated quantities
and are dependent on a constant flow through the hand probe
