The C16 PortaSens II portable leak detector from Analytical Technology is used to check for gas leaks in storage areas, around process equipment and piping, and in confined spaces prior to entry. The detector contains an internal sample pump and a flexible sampling wand to allow pinpoint location of the source of leakage. It can be used to measure over 30 different gases by simply inserting the appropriate sensor into the detector. 800/959-0299; www.analyticaltechnology.com.
