HI-Q - Model AFC-Dual-XX - Dual Range Air Flow Calibrators
If you require visual accuracy over a large flow range, or wish to calibrate a number of air flow units consisting of more than one flow range, select HI-Q’s Dual Range AFC. The Dual Range unit consists of two pressure differential gauges installed in a single cabinet, that precisely measures both the low and high rate of air through a single ...

HI-Q - Model AFC-XX-Series - Analog & Digital Style Low & Medium Volume Air Flow Calibrators
HI-Q Environmental Products Company’s steel constructed, two-component polyurethane painted Air Flow Calibrator (AFC) housings incorporate a precision machined venturi tube to create a pressure differential across a fixed orifice. By varying the air flow velocities, the pressure differentials are measured & recorded against a laminar flow element whose calibration is certified and traceable to the National Institute of Standards and Technology ...

HI-Q - Model FHA-Series - Calibration Adapter Plates (High Flow)
HI-Q Environmental Products Company’s “FHA-Series” adapters are designed to reduce overall pressure drop found during the calibration of standard 4” diameter and 8” x 10” filter paper sampling applications. The FHA’s unique design reduces the overall paper to adapter fitting contact, thereby allowing the maximum obtainable free cross-sectional surface area through which unrestricted air can pass. This is done to ...

HI-Q - Air Flow Calibrator Adapters Fittings
Air Flow Calibrators are generally used to verify the displayed sample flow rate accuracy of complete air sampling systems. Along with the flow measuring device to be calibrated, it is recommended that a “Complete” system for calibration should also include the actual filter holder and filter media in order to duplicate realistic pressure drops experienced in a true sampling environment. The following adapters allow a technician to connect an ...

HI-Q - Model D-AFC Series - All-in-One Digital Air Flow Calibrator
Through the implementation of a baro-metric pressure sensor, thermocouple, precision machined venturi tube and differential pressure sensor, HI-Q’s D-AFC- Series microprocessor based air flow calibrators are used to measure, record, & display instantaneous flow rate (i.e.: CFM, LPM, or CMH), temperature (degrees C or F), and barometric pressure (“Hg or mm Hg). Through onboard calculations the user may also select to display the flow rate ...

HI-Q - Model HFC-XX & HFC-SIDE-XX – HFC-Series - HI-Volume Air Flow Calibrator
The HFC-Series, HI-Volume Air Flow Calibrators, have eliminated the need for cumbersome orifice plates and water manometers. The HFC-XXC series units utilize a precision machined Venturi tube coupled with a pressure differential gauge giving a direct reading in the volumetric units of your choice (i.e. SCFM @ stp) . The unit is calibrated against an in-line N.I.S.T. traceable laminar flow element. The primary calibrator meets the requirements of MIL Std. ...

HI-Q - Model V-FLO-XX-Series - Air Flow Measuring Unit
The V-FLO-XX series units incorporate a flowmeter and a precision-machined venturi tube to create a pressure differential across a fixed orifice which floats the indicating ball in the flowmeter. By varying the flow velocities, the pressure differentials are measured & recorded against a laminar flow element whose calibration is certified and traceable to the National Institute of Standards and Technology (N.I.S.T.). The recorded volumetric flow ...
