The F&J Mini-Calibrator is a small, lightweight microprocessor controlled instrument with sophisticated electronics that measures and displays flow rate corrected to a reference T and P, barometric pressure, and air flow temperature.

The Mini-Calibrator, which is an exclusive F&J design, is a direct reading instrument utilizing a bright LED with large characters that are easily viewed by an operator. A NIST traceable calibration certificate is issued with each calibrator.

The Mini-Calibrator can be utilized as a handheld unit for field calibrations or temporarily mounted in a variety of methods without requiring a level position. The optional hose barb fittings permit easy connection to the air samplers utilizing flexible tubing.

Measurement Accuracy

• Air Flow ± 2% of full scale
• Temperature (Typical) ± 2ºF (1.1ºC)
• Barometric Pressure ± 2% over measurement range

Calibration
Factory calibration is recommended once per year.

Options

• RS-232 interface, including cable.
• All measured and calculated parameters are accessible through RS-232 port to a computer.
