1.5.4.6 Heater and Thermistor
Refer to Figure 7 for the location of heater and thermistor assemblies. Two heater and thermistor
assemblies are used in this instrument to keep the cell temperature at a stable and constant 50 °C.
They are mounted on the top of the measurement cell and below the adjustable mirror mounting
plate.

1.5.5 Main Controller PCA
Refer to Figure 3 for the location of main controller PCA. The main controller PCA controls all the
processes within the instrument. As well as the on-board microprocessor, it contains a battery backed
clock, calendar analog to digital converters and many other circuits for signal processing and control.
The ambient pressure and chassis temperature sensors are also located on this board. The main
controller PCA is located above all other components within the instrument. It pivots on hinges to allow
access to the components underneath.
CAUTION
Never place objects on top of the main controller PCA as it may result in
damage.
1.5.6 Pneumatic Tubing
The pneumatic tubing inside this instrument is specially designed for use in Ecotech Serinus
instruments. It has the flexibility of Silicone tubing with the added inner sheath of PVDF to prevent
contamination of the sample. Care should be taken when removing and inserting the tubing into the
barbed fittings.
