The Informant is the company’s new, technologically sophisticated refrigerant leak detector. It utilizes microprocessor-controlled circuitry. The company says it has the most responsive, patented, heated diode sensor in the industry (2⁄10-of-a-second). The product is designed to automatically and precisely locate refrigerants and detect the exact point of the leak. Additionally, the instrument has the capability to automatically focus on and isolate a leak source even when high levels of background vapors or refrigerant are present. — Bacharach, Inc. Pittsburgh
