Features & benefits include:","Backed by a one-year warranty, the Restek® leak detector is the industry standard for performance and affordability in handheld leak detectors.","Leak Detector Specifications Detectable Gases: Helium, nitrogen, argon, carbon dioxide, hydrogen Battery: Rechargeable lithium ion internal battery pack (12 hours normal operation) Operating Temperature Range: 32–120 °F (0–48 °C) Humidity Range: 0–97% Warranty: One year Certifications: CE, Ex, Japan Compliance: WEEE, RoHS Limits of Detection These gases can be detected with the Restek® electronic leak detector at the following leak rates: Minimum Detectable Gas Limits and Indicating LED 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.
