F&J - Mini-Calibrator Battery Powered Basic Line Power Models
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 operator may select from a reference T and P flow standard or ambient T and P conditions. 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 (additional cost) permit easy connection to the air samplers utilizing flexible tubing.
