• Responds to leaks in less than2 seconds.
• Audible alarmplus LED readout.
• Auto zeroswith the touchof abutton.
• Built-in rechargeable 9 volt battery.
ImproveGCPerformance;SaveYourColumn!
Avoid poor chromatography caused by leaks—leak check your GC system with the Restek Electronic
Leak Detector, the affordable, reliable tool for detecting leaks. Features include internal battery charge
capability, a low-battery indicator, a battery charge indicator light, yellow lights to signal anitrogen leak,
a repositioned on/off switch to eliminate accidentally powering on the unit, and a probe tip design that
prevents debris from entering theunit.The leakdetector’smicrochip technology enables high sensitivity
in a compact unit, the autozero feature allows instantaneous zeroingwith the touchof a button, and the
ergonomic designputs all controls at your fingertips, formaximum ease of use.
Leaks can causedetectornoiseandbaseline instability,waste carrier gas, and shorten column lifetimes, so
leak checks shouldbe a regular part of aGCmaintenanceprogram.TheRestekElectronicLeakDetector
responds in less than2 seconds to leaks of gaseswith thermal conductivities different from air, indicating
leakswithbothanaudiblealarmandanLED readout.The leakdetectordetectsminutegas leaks that can
go undetected by liquid leak detectors.Never use liquid leak detectors on a capillaryGC system; liquids
drawn into the system through the leakswill contaminate the system.
Howdoes theRestekElectronicLeakDetectorwork?
TheRestekElectronicLeakDetectordetectsminute leaksof anygaswitha thermal conductivitydifferent
from air.The referencegas inlet draws in ambient air for comparison to airdrawn into the sampleprobe.
A thermal conductivitydifferencebetween the two indicates a leak, and the leak is revealed to theuser by
both an LED bar graph and an audible tone. The leak detector operates on one rechargeable 9-volt
Ni-MHbattery (included).
Caution:The Restek Electronic Leak Detector is NOT designed for determining leaks of combustible gases. A combustible gas detec-
tor should be used for determining combustible gas leaks under any condition.The Restek Electronic Leak Detectormay be used for
determining trace amounts of hydrogen in aGC environment only.
