MLT 2HT (high temperature measurement)

As a special version MLT 2HT is available for measurements requiring physics thermostated
up to 120 °C. The physical compartment is parted into 2 sections:
- A high temperature (HT) part with special heating and isolation for all components being in
contact with sample gas - SS tubing/fittings, fine dust/safety filter, needle valve, calibration
valve (depending on options). The heated lines are connected in the heated room with sample
gas inlet and outlet fittings.
- The isolation (filter) cell, chopper & detector are located in the lower physical part but outside
of the heated room (need protection from high temperature).
The temperature controller is located in the upper electronical section.
An optional external pump with heated pump head may be located outside of the analyzer
being connected with heated samplegas lines (need of isolation at any connection/ fitting).
