Standard flow
Measure flow rates from 0.1 to 500 ml/min with a resolution of 0.1 ml/min and accuracy of ±0.4 ml/min or 2.5% of reading. Works across eight carrier gases.
7000 GC Flowmeter
Accurate flow measurement. Every time.
Inaccurate carrier gas flows mean inconsistent results. The 7000 GC Flowmeter gives you fast, reliable flow readings so your GC runs the same way, every time.
Accuracy you can trust
25-point calibration traceable to UKAS standards. Set temperature and pressure for your environment and the flowmeter compensates automatically.
Built for the lab bench
Pocket-sized at 68 x 130 x 30 mm and 150 g. Rechargeable battery and a large OLED display. No dead batteries, no squinting at small screens.
Ready for your gases
Measures eight gases used in GC as standard, including helium, hydrogen, nitrogen, and argon. Switch between gases with a single button press.
Flow measurement shouldn't slow you down.
Gas chromatography depends on precision. But setting flows accurately takes time, and small errors in carrier gas flow can throw off your results without any obvious sign that something is wrong.
The 7000 GC Flowmeter was designed and manufactured in the UK to remove that uncertainty, compact enough to carry between instruments, accurate enough for professional laboratory use, and simple enough that anyone on your team can use it. It was built specifically for gas chromatography — the gases, the flow ranges, and the measurement modes all reflect how GC instruments are actually used in the lab.
As one user at the University of Surrey put it:
"Makes setting gas flow rates in GC a doddle."
Three modes. One instrument.
Linear velocity
Select your column diameter in the options menu and the flowmeter calculates and displays linear velocity directly. Switch between flow and velocity with one button press.
Split flow calculation
Measure and store a column flow, then measure the split flow. The flowmeter displays both the flow rate and the split ratio simultaneously.

Frequently Asked Questions
-
Which gases does the flowmeter measure?
The 7000 GC Flowmeter measures eight gases as standard: air, argon, argon/5% methane, carbon dioxide, helium, hydrogen, nitrogen, and oxygen. These cover the carrier and detector gases used in the majority of GC applications.
-
How accurate is the flowmeter?
Accuracy is ±0.4 ml/min or 2.5% of reading, whichever is greater. The 25-point calibration is traceable to UKAS standards, which means it meets the accuracy requirements for professional laboratory use.
-
Does it need batteries?
No. The 7000 GC Flowmeter has a built-in rechargeable battery. You charge it via USB — there are no replaceable batteries to run out at the wrong moment.
-
How often does it need recalibrating?
Recalibration is recommended annually. Ellutia offers a recalibration service, which returns the flowmeter to UKAS-traceable standards and includes a new calibration certificate.
-
Can it measure linear velocity as well as flow rate?
Yes. Select your column diameter in the options menu and the flowmeter calculates and displays linear velocity directly. You can switch between flow rate and linear velocity with a single button press.
-
What is split flow mode?
Split flow mode lets you measure and store a column flow, then measure the split flow. The flowmeter displays both the flow rate and the split ratio at the same time. This is useful for setting up and verifying split injection.
-
Where is it made?
The 7000 GC Flowmeter is designed and manufactured in the UK by Ellutia, based in Ely, Cambridgeshire.
-
Does it come with a calibration certificate?
Yes. Every new flowmeter ships with a calibration certificate traceable to UKAS standards.
-
What is the flow range?
The flowmeter measures from 0.1 to 500 ml/min for most gases, with a resolution of 0.1 ml/min. For carbon dioxide the upper limit is 275 ml/min.
