Gilian Challenger - Air Flow Calibrator

Introducing The Challenger® air flow calibrator for verifying and calibrating Industrial Hygiene Air Sampling Instruments and other air sampling devices. The Challenger® is accurate within 0.75% of reading and provides a LCD indication of Volumetric and Standard flow rate, barometric pressure and ambient temperature.

The heart of The Challenger® is the Venturi. It is made from aluminum and has no sharp edges or moving parts. The instrument, depending on the configuration, is capable of covering the flow rate range of 1 to 30 LPM. The Challenger® offers a 90% recovery of pressure drop which is key to performing a reliable calibration. Because flow through the instrument is uninterrupted, our graphic software provides a continuous output display of all functions. This continuous output makes it very simple to configure The Challenger®. Each unit is furnished with a NIST Traceable Certificate and, after adding batteries (4 AA cells), The Challenger® is immediately ready to meet your calibration needs.
