Binary gas analyser - TCD 8000
Control of pure gases and gas mixtures
General
TCD 8000 Binary gas Analyser uses thermal conductivity technology to perform the measurement of binary gas mixtures
Principle
The TCD 8000 analyser uses a micromechanical silicon sensor and its numerous advantages:
–Fast process measurement
–Short response time (T90), independant of flow rate
–Stable for extremely long periods of time
–No reference gas needed
