Helium Calibrators

Variable-rate Refillable Sniffer Helium Calibrator

Features

The VSLC Leak Standards have been developed specifically to calibrate sniffer leak detectors. The VSLC model is manufactured with a capillary leak element that provides good service in most environments in the usual range for "Sniffing" of 10-3 to 10-6 atm-cc/sec. It should be noted, however, that the capillary is susceptible to clogging in dirty environments and at very small leak rates. With the capillary leak element, the VSLC Calibrators can be used for the larger leak rates of 10-3 and higher, and they have a very low temperature coefficient of 0.2% per °C, which is convenient for applications with wide temperature variations.

Primarily developed originally for calibrating Helium sniffer-type leak detectors, this model is used also to make Calibrators of many other gases and gas mixtures such as hydrogen or helium in nitrogen.

Why choose the VSLC Calibrator ?

  • UNBREAKABLE - stainless steel capillary leak element.
  • LOW TEMPERATURE COEFFICIENT - capillary element.
  • ADJUSTABLE LEAK RATE - each has a 10:1 leak-rate range.
  • CAN BE SET TO AN EXACT LEAK RATE - without the usual manufacturing variance.
  • NO FALSE READINGS - no large dead spaces.
  • EASY PROBE POSITIONING - for repeatable results.
  • MEETS ISO REQUIREMENTS - NIST-traceable, A2LA-
    accredited Calibration Certification.
