Sensidyne's GILIBRATOR-2® System, provides the user with a convenient and highly automated way to check almost any commercially available air sampling pumps for proper air flow function before their deployment. The system consists of an electronic GILIBRATOR-2® Base, which is used with a new soapless piston-type cell, offering the ultimate in convenience and fast setup. These patented interchangeable components are also available as part of kits which can also include a complete calibration diagnostic panel. All cells use a twist-on bayonet design for quick and easy mounting to the base. All are certified for accuracy, traceable to NIST. Sensidyne recommends calibration of your Gilibrator System, whether wet cell or soapless dry cell, at least once a year.
