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 ...
These high volume air samplers are housed in a clear-anodized aluminum outdoor shelter. The units incorporate a maintenance-free, two or three stage centrifugal blower powered by a brushless, variable speed, maintenance-free motor. The motor is controlled by an electronic mass flow sensor that detects changes in the operators pre-set flow rate ...
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 ...
Air Flow Calibrators are generally used to verify the displayed air sample flow rate accuracy of complete air sampling systems. Along with the air 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 ...
The most flexible calibrator design available for laboratory or field use. Mobile venturi tube feature eliminates difficult set-up positions during calibration. Similar to F&J's Digital Air Flow Calibrator line but with a mobile venturi tube. Certified to UL and CSA electrical safety standards by ITSNA (formerly ETL or Edison Testing ...
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 ...
Through the implementation of a barometric pressure sensor, thermocouple, precision machined venturi tube and differential pressure sensor, HI-Q's D-AFC- Series microprocessor based air flow calibrators are useds to measure, record, & display instantaneous flow rate (i.e.: CFM, LPM, or CMH), temperature (degrees C or F), and barometric ...
Accurate and portable. F&J's line of digital air flow calibrators provide accurate, reproducible readings of flow, barometric pressure and temperature. Calibrated using NIST traceable standards. Standard accuracy is 2% and units with an accuracy of 1% are available. Certified to UL and CSA electrical safety standards by ITSNA (formerly ETL ...
HI-Q's AFC-COMPLETE, digital air-flow calibrator, is 'the field technicians first choice' when it comes to air-flow calibration. This microprocessor based air-flow calibrator incorporates the use of a differential pressure sensor, a precision thermistor, an absolute barometric pressure sensor, and a precision machined venturi tube, to measure and ...
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 ...
