The CPH model calibrated leak standard is available for several different gas types and mixes. This model was developed to be compatible with Ultra-High vacuum systems and other critical applications where out gassing and background signals need to be kept to a minimum.

 

The CP model calibrated leak standard, though typically utilized flowing helium is also available flowing several different gas types and mixes. The difference is the CP models shut off valve has a FEP valve packing that seals on the valve stem in the place of the all metal welded bellows model used on the CPH model. This model is an economical option that works well for most applications that utilize o-ring type vacuum fittings.

Features:

  • Unbreakable stainless steel crimped capillary type leak element
  • All welded stainless steel construction
  • All metal vacuum fittings, VCR or Con-flat (Del-Seal), others available
  • Very low temperature coefficient of 0.2%/°C
  • Can be baked to 150°C, 250°C with optional all metal fill valve

 

 

Both of these models are available with various sizes of DOT rated gas reservoirs, the reservoir size is usually dictated by the leak rate to insure an acceptable yearly depletion rate.
