The MFA 9000 gas analyzer is now capable of determining the composition of 13 two-gas mixtures. The instrument also analyzes the common technical gases, including N2, CO2, Ar, H2, He and CH4. Measurements are based on thermal conductivity, and cover pressures from 1.5 to 20 bars, and flowrates of 40 to 150 NL/h. The instrument is capable of alarm functions, detects measuring errors and delivers data via an RS232 interface on a PC, by which the device can be completely controlled and calibrated. — Witt-Gasetechnik GmbH & Co.
