T200M Internal Pneumatic Block Diagram - Standard Configuration
Note
Pneumatic Diagrams do not reflect the physical layout of the instrument.
The most significant differences between the T200H and T200M versions in regards to
pneumatic flow are:
•
A bypass line leading directly from the particulate filter to the exhaust manifold is
present on the T200H, but not in the T200M.
•
The diameter of the critical flow orifice controlling the gas flow into the sample
chamber is smaller and therefore the flow rate of sample gas through the instrument
is lower.
