1. Introduction

The AM-ODO is one of the most compact, durable, and easiest to use dissolved oxygen sensors on the
market. It is an optical sensor that utilizes fluorescence quenching technology. With this technology, the
quenching of fluorophores by dissolved oxygen molecules decreases the fluorescence intensity and
lifetime, the latter of which is detected by a photodetector and allows the dissolved oxygen (DO)
concentration to be quantified accurately and consistently. Unlike polarographic and galvanic
electrochemical technologies used for the measurement of dissolved oxygen, optical technology does
not consume oxygen during measurement. Also, optical technology does not require electrolyte, a
"warm-up" period, nor sample flow. The measured dissolved oxygen concentration is automatically
compensated for by integrated data from the temperature and pressure sensors and sophisticated
algorithms in the firmware.
The AM-ODO-TX is part of the AquaMetrix smart sensor series. Probes in this series are Direct Output
Digital Sensors with the precision of a controller and the accuracy of our core probes. The AM-ODO-TX
also can communicate via RS485 or Modbus protocol.
The AM-ODO-TX has two (2) analog outputs that can be mapped to Percent Saturation (%),
concentration (mg/l) or Temperature. The %-saturation measurement is a function of atmospheric
pressure while the concentration value is also a function of temperature and salinity. The ODO-TX
comes fully calibrated and can maintain this calibration for 1-2 years, depending on the environment it is
installed in.
