LD239 Helium Leak Detector

The smallest, lightest & most sensitive Leak Detector on the market.

GL Sciences’ Gas Leak Detector LD239 adapts thermal conductivity technique between target gases and referential gas.

Being the smallest, lightest and the most sensitive on the market, the LD239 detects up to 0.0005mL/min of helium gas. With the USB port, the LD239 can be recharged easily anywhere.

BENEFITS

• Super compact & light weight (only 95g)
• Easy to use
• Highly sensitive
• Rechargeable USB port

LD239 Helium Leak Detector

Gas leaks can cause detector noise and baseline instability, shorten column life and waste expensive carrier gas. Liquid leak detectors, although inexpensive, can contaminate your GC system. GL Sciences' LD239 leak detector, introduced in 2012 (and replacing it's predecessor, the LD229) is an easy way to quickly identify leaks in your system - check your valves, fittings, and traps for leaks after every maintenance, and after thermal cycling as these can loosen some types of fittings.


LD239 provides the most sensitive He leak detection available in an inexpensive, compact, easily chared (via USB), and easy to use configuration.
