ADS420
Optical dissolved oxygen sensor
Introduction
— The ADS420 sensor is a rugged, reliable instrument
ADS420
designed to deliver accurate dissolved oxygen (DO)
dissolved oxygen sensor
data across a wide measurement range, using the
latest optical technology for DO measurement.
The probe is designed for use with ABB multi-input
transmitters, such as the AWT420 and AWT440,
which feature 'hot-plugging' capability.
Hot-plugging lets new or replacement sensors to be
connected without needing to power down the
transmitter.
When used in conjunction with the optional EZClean
compressed air supply unit (connected to an ABB
adapter nozzle or T-piece), a schedule can be
configured to provide automatic in-situ cleaning of
the sensor.
Measurement made easy
