• Measurement of dissolved oxygen (DO) in aqueous solutions
• Safe single-point calibration
• Two-wire transmitter (with basic and standard versions)
• Electrical isolation of measurement signal (DO) and output signal (mA)
• Problem-free linking to an existing installation (e.g. PLC)
• The full (maximum) version provides a stand-alone solution
• Compensation of temperature, atmospheric pressure and salinity
• Further processing of the temperature of the medium possible (separate
  Pt1000 and two-wire transmitter)
• Setup program provides convenient transmitter configuration/documentation
• Simpler, safer servicing by replacing modules
• Backlit display, i.e. easy to read even in darkness (for the maximum version)
• Comprehensive range of accessories

The JUMO dTRANS O2 01 two-wire transmitter is used for the measurement of dissolved oxygen in aqueous solutions. It provides an electrically isolated 4 — 20 mA output signal corresponding to the oxygen content. The instrument can be configured through a setup program or from a terminal box / operating unit (available as an option). The temperature of the medium can be acquired through a Pt1000 in the two-wire transmitter and further processed (from the standard version and above, also as 4 — 20 mA two-wire signal).
The measurement is made with an electrochemical, membrane-covered sensor. The microprocessor circuit incorporated in the two-wire transmitter takes account of the temperature, atmospheric pressure and salinity (salt content) factors. The sensor is of modular design and is easy to maintain and replace.
