Primary Standard Air Flow Calibrator [Gilibrator-2]

The Gilibrator-2 System provides users with a convenient and highly automated way to check almost any commercially available air sampling pump for proper air flow function before deployment. The system consists of an electronic Gilibrator-2 Base which is used with any of three sizes of wet bubble cells. 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 and traceable to NIST.

 

Calibration Cells

Three bubble cells are available, for air flow ranges of 1 to 250 cc/min (low flow cell), 20 cc/min to 6 LPM (standard flow cell) and 2 to 30 LPM (high flow cell). These interchangeable wet cells generate perfect bubble films at the touch of a button. An infrared sensor reads the bubble flow rate, which is then calculated and displayed.

 

Gilibrator-2 Base

Easy to operate, microprocessor-controlled unit features simple on/off and reset touchpad with large LCD screen that displays flow rate, the calculated average of multiple flow samples in a series and the sample number. Light in weight, it operates with either AC power or rechargeable batteries (8 hours life) for easy portability in either the lab or the field.
