Agilent Digital Bubble Flowmeters have been making flow measurement easy for years. Today, they are still widely used to measure GC flows, calibrate air sampling pumps, and verify various gas flows. The Optiflow series offers the widest range of flow rates and allows you to visually ensure gas flows. This tried and true flowmeter measures volumetrically and therefore can measure any gas composition with the push of one buttom and the squeeze of a bulb.
Optiflow
Wide flow range from 0.1 to 50 mL/min (Optiflow 420) up to 5 to 5000 mL (Optiflow 650)
9V Long-lifetime battery
Available with hard field case (Models 570 and 650 only)
Optiflow 420
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
Optiflow 570
Want a bubble flowmeter for measuring carrier, makeup, injection port, and detector gases? The Optiflow 570 handles most of your GC needs. We also manufacture Optiflow 570 in a hard metal case, which makes it portable and field ready.
Flow range— 0.5 to 700 mL/min for the Optiflow 570
Available in hard field case (Optiflow 570 only)
Split ratio measurement
+/-3% accuracy
Optiflow 650
If you calibrate air sampling equipment, verify mass flow controller settings, or monitor higher gas flow rates, these Optiflow flowmeters are simple and efficient.
Flow range— 5.0 to 5000 mL/min for the Optiflow 650
+/-3% accuracy
Available in hard field case
Measures both positive and negative flow sources
Optiflow 1000—Liquid Flowmeter
Optiflow 1000 measures liquids! Verify and set HPLC column flow rates with the Optiflow 1000.
Flow range— 1 to 30 mL/min
+/-2% accuracy
