Accurate and repeatable gas flow measurement is fundamental to obtaining good results from your thermal desorption-gas chromatograph. The traditional bubble flowmeter, relying as it does on the reaction time of the operator, is a potential source of error.
The digital flowmeter eliminates this source of error and makes gas flow easement easier and more accurate. The flowmeter allows measurement of eight gases: air, argon, argon–5% methane, carbon dioxide, helium, hydrogen, nitrogen and oxygen, in the range 0.1–500 mL/min. Rresolution is 0.1 mL/min and accuracy is typically better than ±2.5%.
