F&J - Digital Laminar Flow Element Calibrators for Air Samplers
From F&J - Air Flow Calibrators - Digital Calibrators
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.
Notable Features
- Differential Pressure Flow Sensor
- Display of flow in CFM, LPM or M3/min. by operator selection (LED display)
- Standard accuracy: ±2% Full Scale
- Flowrates displayed are corrected to a factory settable Reference Temperature and Pressure (4 options available)
- Classical STP - 0° C - 1 Atm
- Normal T and P - 20° C - 1 Atm
- Modified Normal T and P - 70° F - 1 Atm
- Standard Ambient T and P - 25° C - 1 Atm
- Display of temperature in metric or English units
