The Detect-F is the first handheld gas leak detector to offer detection of both CO2 & Refrigerant gases. Using unique patented sample technology the Detect-F provides the convenience to perform leak detection with a single instrument selectable for both gas types. The Detect-F uses semi-conductor and electrochemical sensors to ensure high responsiveness of both refrigerant gases and CO2. The choice of sensors present the advantage of being small, low cost and fast responding. Equipped with a progressive audible alarm and flashing LED indication, the Detect-F quickly targets the source of the leak. The easy grip handle allows the user to comfortably carry out gas leak detection. A high impact rugged design and flexible metal hose increases accessibility for those hard to reach places.
