Optiflow Series: Dependable bubble flowmeters

Agilent Digital BubbleFlowmeters have been making flow measurement easy for years. They are widelyused to measure GC flows, calibrate air sampling pumps, and verify various gasflows. The Optiflow series offers the widest range of flow rates and allows youto visually ensure gas flows. This tried and true flowmeter measuresvolumetrically and thereforecan measure any gas composition with the push ofone buttom and the squeeze of a bulb.

	The Optiflow 420 is the best bubble flowmeter for measuring low gas flow rates–especially GC columns. Flow range–0.1 to 50 mL/min +/- 3% accuracy 9-V long-lifetime battery
	The Optiflow 570 handles most of your GC needs. Manufactured in a hardmetal case, this makes it portable and field ready. Flow range–0.5 to 700 mL/min Available in hard field case Split ratio measurement +/- 3% accuracy
	If you calibrate air sampling equipment, verify mass flow controller settings, or monitor higher gasflow rates, the Optiflow 650 flowmeters are simple and efficient. Flow range–5.0 to 5000 mL/min +/- 2% accuracy Available in hard field case Measures both positive and negative (vacuum) flow sources
