Ferret Instruments’ GasLink (F-14) boasts the largest display on the market; at 3″ x 9.5″ the backlit display supports double high, double wide characters allowing the unit to be read as easily from a distance in the service bay as in the operator’s hand. And the keypad serves left- and right-handed technicians well. Seven keys manage complete operation including access to detailed help menus. The GasLink displays and records up to three hours of “real time” data on five gases, RPM and temperature. And three display options allow the operator to choose between composite information, bar graphics or the Big Digit Display. The unit also uses a heavy-duty pump with a wet filter system to ensure long pump life. Contact: Ferret Instruments, Inc., 1310 Higgins Drive, Cheboygan, MI 49721-1061.
