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 REFRIGERANT SNIFFERS

• Choose the RLS Model when:

• You need to test to an exact leak rate or must be able to vary the rate.
• You want the calibrator to operate for a year or longer without refilling.

• Choose the FSLTC Model when:

• You can easily refill the reservoir with refrigerant vapor periodically.
• You need to specify and test to a specific leak rate.

• Choose the FSLTL Model when:

• You want the calibrator to operate for a year or more without refilling.
• You can test within a broad range of leak rates if you know the specific rate.

• Choose the RSC Model when:

• You need to test only with R134a.
• You want the calibrator to operate for a year or more without refilling.
• You can test within a broad range of leak rates if you know the specific rate.
