Ordering Information
The FSLT Calibrators can be ordered for a single specified Helium leak rate within a wide range of values. When ordering or requesting a quotation, please provide the Part Number and also specify the Leak Rate requested using the full description of both the rate and the leak-rate units that you are requesting (for example: 2.0x10-4 atm-cc/sec). Also, please specify the manufacturing variance ("tolerance") that you can allow on that Leak Rate as +/- 40%. or +/- 15%. The usual manufacturing variance is +/- 40% of the requested rate. (For the example rate above, the allowable range as manufactured would be from 1.2 to 2.8x10-4.) A "Special Range" variance is available of +/- 15%. (For the example, this would allow the leak rate, as delivered, to be from 1.7 to 2.3x10-4.) For this special manufacturing variance, an "-SR" is added to the end of the Part Number and there is an addition of $200 to the price of the Leak.
Please contact us for assistance if you have any technical or ordering questions or want a customized Leak or manufacturing variance. Other leak-rates units, such as Torr-liters/sec, can be specified and calibration data will be reported in the units requested.

Part Number Build-Up
The FSLT Series Part Numbers are constructed as follows:
FSLT-X-HE-1/4T-YYYYY-WFV
where X = the code for the Leak Rate Range required,
and YYYYY = the code for the size of reservoir required. The X and Y codes are listed in the table right.
As noted above, a -SR is added to the end of the part number to identify the special manufacturing variance of +/- 15% in the Leak Rate instead of the standard +/- 40% variance.
The FSLT model is identified as a Fixed-rate Calibrated Leak with a Teflon-permeation leak element and is specifically designed for calibrating sniffer type leak detectors. The "He" in the part number identifies this as a Helium Calibrated Leak and the "WFV" designates the particular Teflon-packed stainless steel fill valve used on the product.
