FSLTL Calibrated Refrigerant Leaks
The FSLTL Refrigerant Leak Standards have been developed specifically to calibrate sniffer leak detectors and to avoid the clogging problems common to Calibrators that have a capillary leak element. This is particularly important for small leak rates of 0.5 ounce/year and less.
The FSLTL Accu-Flow™ Calibrated Leaks are available for all old and new refrigerants, for a wide range of standard leak rates from 0.1 to 3 oz/year, and for custom rates. They can be used with all makes of leak detectors.
Why choose the FSLTL Calibrator ?
- WILL NOT CLOG – permeation leak element
- SPECIFY ANY REFRIGERANT – old or new
- FIVE LEAK RATE RANGE – you can choose
- WIDE LEAK-RATE CHOICE – 0.1 to 3 oz/yr
- NEVER NEED REFILL – lasts for years
- SIMPLE TO OPERATE – minimal user training
- NO FALSE READINGS – no large dead spaces
- EASY PROBE LOCATION – for repeatable results
- MEETS ISO REQUIREMENTS – NIST-traceable, A2LA-accredited Calibration Certification
Using the Calibrator
To calibrate a Refrigerant Sniffer Leak Detector, the operator places the tip of the sniffer probe briefly into the tapered recess at the point source of refrigerant vapor flow of the FSLTL. The leak-rate reading of the Detector is then adjusted to the Leak Rate of the Calibrator, as provided by VTI on the Calibration Tag. A second reading is obtained in the same way to assure the calibration of the detector.
It should not be necessary for you ever to refill the FSLTL Calibrated Leak. However, it should be compared periodically to another Calibrated Leak if available, and returned to VTI for recalibration in accordance with your Quality Assurance/ISO schedule requirements.
Reliable Calibration of the Sniffer Leak Detector is fundamental to effective operation. The “point-source” design for the gas flow assures that excessive calibration gas will not accumulate in “dead spaces” to cause erroneous high readings during detector calibration, which can later result in “passing” bad product.
The FSLTL Calibrators can be ordered for almost any Refrigerant and for a wide range of leak rate ranges. When ordering or requesting a quotation, please provide the Part Number and also confirm the Leak Rate Range requested using the full description of the rate and the units (for example: 0.04 to 0.10 ounce/year) . The Leak Rate provided will be within this manufacturing-variance range and the actual rate, as calibrated, will be recorded on the Calibration Tag. If you have any technical or ordering questions, please contact us for assistance.
Part Number Build Up
The FSLTL Series Part Numbers are constructed as follows:
where XXXX = the code for the Leak Rate required
where YYYY = the “R” code of the Refrigerant required. Common refrigerants are listed below and others are available. The leak rate units, codes, and ranges available are listed in the table below.
Most Refrigerants (old and new) in use today are available in FSLTL Leaks.
Common Examples: R-12, R-404A, R-507 (AZ-50), R-22, R-410A, SF6 (Tracer Gas), R-134A, R-502, Halons
