2.1 ANALYZER OVERVIEW
Figure 2.1: Analyzer overview.
The 9065C has two main sections:
1. Buttons on the top of the instrument
2. Mechanical components:
a. The throttle valve
b. The two hose sockets for the sample hoses

Introduction

The instrument consists of four parts that are connected to each other
1. The electronics housing
2. The upper housing
3. The battery pack
4. The measurement chamber
2.2 O2MEASUREMENT PRINCIPLE
The O2measurement is based on measuring the luminescence of a layer that is sensitive to
oxygen. The luminescence changes according to the partial oxygen pressure. The quantity of
dissolved oxygen gas in the liquid is calculated with the aid of the measured partial oxygen
pressure and the temperature.
The oxygen sensor optically measures the liquid’s O2content based on the luminescence
measurement principle, where an oxygen-sensitive layer is exposed to blue light. As a result,
molecules in the oxygen-sensitive layer are excited.
In the absence of oxygen, the molecules light up red. In the presence of oxygen, the oxygen
molecules collide with the molecules in the oxygen-sensitive layer. The molecules that collide
with oxygen no longer light up. Through this process, a link is created between the oxygen
concentration and both the light intensity and the speed at which the light intensity is reduced.
The light intensity reduces when the oxygen concentration is higher, whilst the light intensity
reduces at a faster speed.

Figure 2.3: Luminescence in the absence of oxygen (1) and in the presence of oxygen (2).
The oxygen content is calculated using the time difference between the exposure to the blue light
and the molecules lighting up (phase shift) and the product temperature. The sensor in the 9065C
is located behind the inlet and before the throttle.
