Helium Sniffer Calibrators: Fixed and Variable Rates
VTI provides both Variable-Rate and Fixed-Rate Helium Sniffer Calibrators in either the Crimped Capillary or Teflon Permeation type design. The variable leak rate models (shown) are provided with pressure vs leak rate calibrations to allow the operator to change the leak rate by changing the reservoir pressure. The Fixed and Variable Rate Capillary designs (FSLC and VSLC Models) have leak rates that are insensitive to temperature. The popular Fixed and Variable Teflon Permeation designs (FSLT and VSLT Models) are not susceptible to plugging.
