2 Introduction
2.1 Product Identification
There is a rating plate on the sensor with the following information that you can use to uniquely identify the product:
Serial number
Product type
Power supply
Interface
In addition to the product bar code, the rating plate includes the TriOS Mess- und Datentechnik GmbH logo and the quality
label.
Please note that the specifications given here are for illustration purposes only and may be different depending on the version
of the product.
The Dissolved Oxygen sensor applies the luminescence-based optical measurement technology and measures reliably and
accurately. With low consumables and maintenance required, the Dissolved Oxygen sensor gives an immediate return on the
investment. The only intervention required is to replace the Membrane Cap every two years.
The sensor can even be used in applications with very weak flow of water.
The sensor offers the following advantages:
• Low operating costs due to reduced maintenance work (no electrolyte changes)
• Greater calibration intervals due to low drift behaviour
• No polarization voltage required
• High measuring accuracy, even for low concentrations
• Rapid response times
• No minimum inflow (no oxygen consumption)
The sensor features excellent interference immunity thanks to the integrated preamplifier and digital signal processing. The
measured value for dissolved oxygen is automatically compensated with the temperature, air pressure, and salinity (salt con-
tent), and transferred without interference to the connected display unit and controller via a digital interface. The membrane
cap is easy to replace, meaning the sensor is very easy to maintain. The current calibration data is saved directly in the sensor
electronics. As a result, the Plug and Play function of the system is enabled without the need for recalibration. The sensor also
includes a log book containing the last ten successful calibrations in the form of a ring buffer.
