9408 series

Dissolved oxygen systems

Measurement made easy

Introduction

The 9408 Series dissolved oxygen system comprises 
a flat-ended sensor mounted into a relatively large 
diameter spherical flotation collar. This form of 
construction presents to the sample a surface on 
which it is difficult for rags and other large solids to 
lodge. For more demanding applications, on-line 
cleaning is available using the water wash option.
