INTRODUCTION
The DOX8HS submersion type holder is used to hold a sensor. This holder will keep the sensor
immersed in the solution at all times for continuous measurement regardless of major changes in
the level of the solution to be measured. The use of a submersion type holder with a jet washing
device enables automatic cleaning of the front end of the sensor at desired intervals by a water
jet or air jet without the need to remove the sensor.
To fully exploit the capabilities of this product, read through the user's manual before use.
Throughout this instruction manual important items with respect to handling are indicated by a
