The Met Lab Series of high-precision primary flow standards offers

exceptionally low uncertainties to meet the most stringent laboratory

and industrial process control requirements.

The Met Lab 800 Series combines our Proven Bios DryCal Technology

with interchangeable flow cells to achieve precise, primary measurements

over an incredibly broad flow range; from 0.5 sccm up to 100 slpm.

Our latest flow cell, the ML 800, offers an extended gas flow measurement

range of 1-100 lpm with a standardized flow accuracy of 0.15%. This expanded

flow cell offers a piston prover with a high purity graphite piston (75mm).

The ML-800 offers gas measurement technology that is largely independent

of gas species.

The 800 series consists of 5 interchangeable flow cell models, the table below details each model and its specific attributes:

• 0.5 sccm – 100 slpm Flow Range
• 0.25% Measurement Uncertainty (0.5 – 50 sccm)
• 0.15% Measurement Uncertainty (5 – 100,000 sccm)
• 5 Interchangeable Flow Cells
• 100:1 Turndown Ratio
