1.2 INTENDED USE

The Waltron 9065 Dissolved Oxygen Analyzer utilizes new luminescent technology for
measuring dissolved oxygen in water at ppb levels. Luminescent technology has unique features
and benefits compared to traditional dissolved oxygen sensing technologies. The 9065 provides
high accuracy with excellent long-term stability. The 9065 Dissolved Oxygen Analyzer can be
used in a variety of online analysis applications throughout many different industries.

The 9065 must be connected to a sample line. The connections to the flowcell are ¼” (6mm)

Swagelok fittings. The dissolved oxygen must be measured in a full, flowing sample line. Using
the sensor in a pipe that is not full or taking the measurement while the product is not flowing
will cause errors or will it cause damage to the device.

Features:

 Analysis range: 0.10ppb – 2000ppb (others available upon request)
 No calibration for up to 2 years
 Extremely fast response
 No sample interference
 Excellent results regardless of sample flowrate
 Use in liquid and gas applications
 High temperature alarm
 Multiple sensor configuration

Benefits:

 No sensor maintenance (no membrane, no electrolyte)
 Simple operation
 Compact design

NOTE:

Instructions for the correct and effective use of the
instrument.

WARNING!

Incorrect or careless use may cause serious damage to the
instrument.

Incorrect or careless use may place the user or the
surroundings in DANGER.

WARNING!

To avoid a short circuit, never insert metal objects into the
connector.

The use of chlorite-based or fluorine-based cleaning
products is not permitted. These may cause damage to the
instrument.

Ensure that the pipe is not pressurized and that the
instrument is disconnected from the power supply
during assembly and disassembly. This will prevent
electric shocks.

During CIP/cleaning, the outside of the instrument may
become hot. The sensor will turn itself off automatically
when the inside of the sensor reaches a temperature of
65C. Do not touch the outside of the instrument.

2. Sensor Housing

The bottom of the sensor housing provides the location of the dissolved oxygen sensor, shown in
the figure below.

The 9065 coatingholder is recognizable by its hexagonal shape.

Figure 2.3: 9065 Coatingholder.

MEASUREMENT PRINCIPLE

2

The O2 measurement 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 O

content based on the luminescence

2

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.

Introduction

14

Waltron User Manual
9065 Luminescent Dissolved Oxygen Analyzer

Figure 2.4: 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 9065 is
located behind the inlet and before the throttle.
