1. Overview
1.1 Features of the DOX8HS Submersion Type
Holder
• Holds the sensor in place without being affected by the conditions of the solution to be
measured
The sensor is steadily held at the measurement point no matter how fast the solution flows.
The material of the holder can be selected to suit the temperature of the solution to be
measured or corrosive substances it contains. Only the front end of the sensor is exposed to
the solution to minimize the likelihood of problems.
• Sensor is held at a tilt angle of 45° to allow stable measurements
Measurement results are less likely to be affected by air bubbles enabling noise free
measurements in a wide range of processes.
• Sensor front end is automatically cleaned at regular intervals at the place at installation
Water jet or air jet cleaning substantially reduces dirt at the front end of the sensor.
This makes it possible to reduce the frequency of maintenance even in highly contaminated
solutions.
