Analytical Index Technologies Inc. (www.aituniversal.com) showed the AIT-SmarTec® liquid refrigerant identifier. Company spokesperson Remy Singh said the product "identifies refrigerants in their liquid state rather than vapor state, and, as such, eliminates errors caused by other non-dispersive infrared hand-held methods."
Advanced Test Products-SPX (www.spx.com) showed a UV leak detector and dye kit said to handle a wide range of situations. The system can be used to pinpoint what the company called "elusive, intermittent, and multiple simultaneous leaks."
