- The Gilian Challenger® is an 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.
- Challenger® offers a 90% recovery of pressure drop which is key to performing a reliable calibration. Because fl ow 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 high and low flow venturi and NIST Traceable Certificate. Requires 4 AA batteries (not included).
