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 any of three sizes of wet bubble cells. It can also be 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.

Wet Cells
Three bubble-type cells are available, for air flow ranges of:
• 1 to 250 cc (low flow cell);
• 20 cc to 6 LPM (standard flow cell); and
• 2 to 30 LPM (high flow cell).
When used with the GILIBRATOR-2® Base, these unique, interchangeable wet cells automatically generate perfect bubble films at the touch of a button, using infrared technology to read the bubble flow rate, which is then calculated and displayed.
Piston Cell
This unique cell uses a soapless piston-type design to provide a primary flow standard for air flows from 1 to 5 LPM. Based on a nearly frictionless piston, it is ideal for field or lab environments where the user may prefer a liquidfree instrument, assuring accuracy and reproducibility.
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 Nicad batteries (8 hour life), for
easy portability in either the lab or the field.
GILIBRATOR-2® Diagnostic Kit
Offers the industrial hygienist a complete, portable calibration laboratory. Consists of GILIBRATOR-2®
Base with either three wet bubble cells or one soapless piston cell in a cushioned carrying case, with a full
diagnostic panel built into the top lid of the case. The panel uses an interchangeable rotameter design for
2 to 5,000 cc flow capability and will run any of several diagnostic tests:
• “Load” simulation – Offers two load simulations for high and low flows to
imitate line back-pressures.
• Back pressure reading – A built-in Magnehelic® gauge allows visual monitoring
of in-line back pressures up to 30" H2O.
• Leak checking – Built-in Magnehelic® gauge allows visual leak testing and
monitoring capabilities.
• Pump flow adjustment – Rotameters allow instant visual indication of
approximate flow rates, assisting in properly adjusting air flows.
