Product Description
Restek's portable electronic leak detector is specifically designed for use with gas chromatography (GC) systems. It detects small leaks of any gas with a thermal conductivity different from air. The reference gas inlet (Figure 1) draws in ambient air for comparison to gas drawn into the sample probe. The intensity of a leak is indicated by both an LED light display and an audible alarm. The following table explains how to interpret the LED display.
NOTE: The leak detector is not a quantitative device, it is a qualitative measure of the location, intensity, and nature of a gas leak.

A universal AC power adaptor (U.S., European, UK, Japan and Australian plugs included).

SPECIFICATIONS:
Detectable Gases: Helium, nitrogen, argon, carbon dioxide, hydrogen
Battery: Rechargeable lithium ion internal battery pack (12 hours normal operation)

LIMITS OF DETECTION:
Gases that can be detected Minimum Detectable Leak Rate Indicating LED Light Color:
Helium 1.0 x 10-5 red LED
Hydrogen* 1.0 x 10-5 red LED
Nitrogen 1.4 x 10-3 yellow LED
Argon 1.0 x 10-4 yellow LED
Carbon dioxide 1.0 x 10-4 yellow LED

Gas detection limits measured in atm cc/sec.

Avoid using liquid leak detectors on a GC! Liquids can be drawn into the system and/or into the leak detector.

*Caution: The Restek electronic leak detector is designed to detect trace amounts of hydrogen in a noncombustible environment. It is NOT designed for determining leaks in a combustible environment. A combustible gas detector should be used for determining combustible gas leaks under any condition. When using it to detect hydrogen, the Restek electronic leak detector may only be used for determining trace amounts in a GC environment.
