Wetted Materials: 304SS
Measurement Range (Volume %): 0.1% to 50%.
Accuracy: (To obtain the specified accuracies, take the average of three samples.)
At low limit of 0.1%, actual air content may be between 0.075 and 0.125%.
At 10% air, actual air content may be between 9.9 and 10.1%.
At high limit of 50%, actual air content may be between 49 and 51%.
In general, Error = +/-( 0.025 + 0.00975 * Air)
Calibration: The tester is calibrated by running samples of 0% air (for example water
with no entrained air). The microprocessor automatically calculates the calibration constant.
Seals: Buna Rubber
Weight: 7 lbs (3.2 kg)
Batteries: Three 9-volt, life 8-12 hours of continuous operation
Media Isolation: Cylindrical portion of the tester is compatible with fluids not
corrosive to 304 SS, provided that the vent line is not exposed to corrosive fluids.
The electronics enclosure is not environmentally isolated, and may not survive
fluid spaying, submergence, or exposure to corrosive gases. The QuickAir must be
stored in a clean, dry area when not in use.
Temperature: Cylinder portion of tester is limited to operation between 32 and 200 F.
Operation above 120 F may require re-zeroing of pressure transducer due to
temperature effect on the pressure transducer zero. The electronics may be stored
at temperatures between 32 and 150 F, and may be operated at ambient
temperatures between 40 and 110 F.
Pressure: The tester is designed to obtain samples at atmospheric pressure. During
testing, the normal maximum pressure is approximately 60 psig (4 bar gauge). The
pressure transducer is rated for a maximum operating pressure of 100 psig (6.8 bar gauge). It will remain linear to an overpressure of 200 psig (13.8 bar gauge), and will fail at 400 psig (27.2 bar gauge).
