SELECTION OF CALIBRATORS FOR SNIFFER LEAK DETECTORS

Reliable sniffing-type leak detection requires frequent calibration of the entire leak testing setup by testing and calibrating at the sniffer probe itself.

VTI offers a wide range of Calibrated Leak Standards for sniffer detector calibration so that one is sure to meet your particular requirements. Designed specifically for sniffer calibration, VTI's leak standards feature a "point-source" design for the helium or refrigerant flow to avoid erroneous readings.

Models are available for helium, refrigerants and virtually all other gases, as well as for a wide range of leak rates. Fixed-leak-rate calibrators are available, as well as "variable-rate" models which have a 10-to-1 adjustable range. Models are available with Teflon-permeation leak elements or crimped stainless-steel capillary leak elements, the choice depending on the gas, leak rate and use environment.

VTI's experts are always eager to help you select the best model - technically and cost - for your application. Without obligation, of course.

CHOOSING A CALIBRATOR FOR HELIUM SNIFFERS

  • Choose the VSLT Model when:

  • You want to be able to vary the rate over its 6:1 leak-rate range.
  • You can easily fill the reservoir with Helium gas periodically.
  • You want the Teflon-permeation leak element that will not clog.

  • Choose the VSLC Model when:

  • You want to be able to vary the rate over its 10:1 leak-rate range
  • You can easily refill the reservoir with Helium periodically.
  • Your relatively clean plant/lab will not clog the capillary leak element.

  • Choose the FSLT Model when:

  • You want to calibrate at a single fixed leak rate.
  • You want the calibrator to operate for a year or more without refilling.
  • You want the Teflon-permeation leak element that will not clog.

  • Choose the FSLC Model when:

  • You want to calibrate at a single fixed leak rate.
  • You want the calibrator to operate for a year or more without refilling.
  • Your relatively clean plant/lab will not clog the capillary leak element.
