HELIUM CALIBRATED LEAK STANDARDSFSLC Sniffer-Detector Calibrators

The FSLC Model CALIBRATORS FOR SNIFFER-TYPE HELIUM
LEAK DETECTORS (also available for SF6 and other gases)
The FSLC Leak Standards have been developed
specifically to calibrate sniffer leak detectors. The
FSLC model is manufactured with a capillary leakelement, which makes it susceptible to clogging in dirty
environments and for very small leak rates. However,this model provides good service in most environmentsin the usual range for “Sniffing” of 10-4 to 10-6 atmcc/sec, and also can be used in special configurations
for leak rates as large as 0.1 atm-cc/sec (10-1 atmcc/sec).
Primarily developed originally for calibrating Helium
sniffer-type leak detectors, this model is used also tomake Calibrators of Sulfur Hexafluoride (SF6), Neon,
Carbon Dioxide, Hydrogen and other gases.

Choosing the FSLC Calibrator
UNBREAKABLE – stainless steel capillary leakelement.
FIXED LEAK RATE – for simple operation.
SPECIFY AN EXACT LEAK RATE – your testpoint.
WIDE LEAK-RATE CHOICE – the full range that isused for sniffing.
LOW TEMPERATURE COEFFICIENT – flow rate
does not change with temperature.
EASY PROBE POSITIONING – for repeatableresults.
SUITABLE FOR SF6 and OTHER GASES –contact the factory with your requirements.
MEETS ISO REQUIREMENTS - NIST-traceable,
A2LA-accredited Calibration Certification.

ORDERING INFORMATIONThe FSLC Calibrators can be ordered for a single specified leak rate within a wide range of values. Whenordering or requesting a quotation, please provide the Part Number and also specify the Leak Raterequested using the full description of both the rate and the leak-rate units that you are requesting (forexample: 2.0x10-4 atm-cc/sec). Also, please specify the manufacturing variance (“tolerance”) that you canallow on that Leak Rate as +/- 40%. or +/- 15%. The usual manufacturing variance is +/- 40% of the requestedrate. (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, asdelivered, to be from 1.7 to 2.3x10-4.) For this special manufacturing variance, an “-SR” is added to the endof 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 Leakor manufacturing variance. Other leak-rates units, such as Torr-liters/sec, can be specified and calibration
data will be reported in the units requested. Calibrated Leak Standards of many gasses other than Helium(such as SF6, Ne, H2, CO2) can also be provided in the FSLC model. Please ask us about availability.
“Special Orders” are everyday products for us ! Just let us know what you need !
