Zefon Field Rotameters are a low cost way to measure airflow in air sampling applications. They feature a durable acrylic housing with direct reading scales printed on them. Available in three different flow ranges covering a range of 0.2 through 30 LPM. Operation and maintenance are very simple; only a few common sense precautions must be observed to assure long, trouble-free service. Features: Scales are large (average 4" length) and easy to read The front scale location and white background provides excellent visibility. The direct reading scales are hot stamped into the plastic and will not wear off. Mid-range calibration is established with a master flowmeter. Durable and attractive construction The machined acrylic bodies of the Zefon rotameter flowmeters are practically unbreakable. Fabrication is backed by over 60 years of experience in acrylic instrument machining. The tapered bore is precision machined to a smooth surface that provides perfect visibility of the indicating float. Accuracy is ±3% Easy, simple way to perform calibration measurements in the field. Includes Hose barb, Tygon tubing, and luer adapter.
