Polymetron 9582 dissolved oxygen analyzer

Category: Polymetron

-Typical applications are power plants, semiconductor plants, etc., suitable for the analysis of dissolved oxygen at low concentrations (ppb) such as deaerated water. -Characteristics and advantages Pre-installed membrane modules, membrane replacement work only takes a few seconds, low detection limit, fast calibration process: less than 15 minutes to complete the calibration from ppm level (air) to ppb level (process), versatility 9500 controller, easy to integrate and simple to install. Working principle The measurement of dissolved oxygen is based on the well-known Clark battery principle. The oxygen-permeable membrane isolates the water sample from the electrode, so no sample adjustment is required. Due to other reducing or oxidizing ions.

Product description

Parameters

Technical indicators

- typical application

Power plants, semiconductor plants, etc., are suitable for the analysis of dissolved oxygen at low concentration (ppb) such as deaerated water.

-Features and benefits

The pre-installed membrane module only needs a few seconds to replace the membrane

Low detection limit

Quick calibration process: calibration from ppm (air) to ppb (process) can be completed in less than 15 minutes

The universal 9500 controller is used for easy integration and simple installation.

- working principle

The measurement of dissolved oxygen is based on the well-known Clark battery principle. The oxygen-permeable membrane isolates the water sample from the electrode, so there is no need to adjust the sample. Since other reducing or oxidizing ions cannot pass through the gas-permeable membrane, they will not cause interference.

A constant voltage is applied to the two electrodes to keep the potential of each electrode constant. The gold working electrode (cathode) reduces dissolved oxygen to hydroxide ions:

O2 + 2H2O + 4e--> 4OH

The oxidation reaction takes place on the surface of the large silver electrode (anode):

4Ag + + 4Br--> 4AgBr + 4e-

The oxidation-reduction reaction produces a diffusion current, which is proportional to the dissolved oxygen concentration.
