Air Liquide Electronics has replaced two Ion Science gas leak detectors that have been in service at its Dallas site in the US for over 20 years.

The new GasCheck G devices will be used daily at Air Liquide’s semiconductor manufacturing facility to check for gas leaks after high pressure cylinder changes.

The robust, handheld instruments feature advanced systems of microthermal conductivity for advanced gas leak detection sensitivity down to parts per million (ppm) level.

The GasCheck G range can detect leaks from almost any gases or mixtures, with an LCD display, LED indicator and audible alarm activated when a gas leak is discovered. The models also automatically ‘zero’ to the ambient air when switched on.

Jana Wu, TGCM Gas Specialist at Air Liquide said the upgrade will give the company’s cylinder technicians “complete confidence in leak test results.”

“We chose the GasCheck G2 model because it provided an actual reading instead of a bar graph type output. It can also be adjusted for sensitivity which is an advantage,” Wu added.

Air Liquide Electronics is a major supplier of gases and solutions for the semiconductor, photovoltaic and flat panel display markets.
