3. The ROX sensor is automatically wiped during field studies to eliminate effects of fouling. The
Rapid Pulse sensor can be wiped, but only if a 6600EDS V2-2 sonde is used.
In addition, the ROX DO sensor has NO flow dependence, giving it a large advantage over systems which
utilize steady-state membrane covered polarographic oxygen sensors. This advantage is minimal relative
to the YSI Rapid Pulse technology which is effectively flow-independent in monitoring studies and shows
only minimal flow dependence (ca. 3%) in continuous-on sampling studies.
What is the warranty period for the ROX DO Sensor?
The probe is warranted for 2 years and the sensor membrane assembly is warranted for 1 year. See
Section 9 of this manual for details of the YSI warranty policy.
What sondes can use the ROX DO Sensor?
The ROX Sensor can be used with any existing or new YSI 6-series sonde which contains an optical port.
Currently available sondes which support the use of the ROX sensor are 600 OMS V2-1, 6820V2-1,
6820V2-2, 6920V2-1, 6920V2-2, 6600V2-2, 6600EDS V2-2, and 6600V2-4 which were manufactured
after June 1999. If you have an older sonde with an optical port and want to determine whether it will
support the use of the ROX sensor, contact YSI Technical Support. They will be able to evaluate the
compatibility of your sonde with the ROX sensor by giving you a few simple software commands to issue
at the “#” sign of your sonde.
If I want to use the new ROX DO Sensor with my existing sonde, what else do I have to do?
In order to use the ROX technology on an existing YSI 6-series sonde, you must do the following:
• Upgrade the firmware in your sonde from the YSI Website (ysi.com) to Version 3.00 or higher.
• Upgrade your EcoWatch for Windows PC software from the YSI Website to Version 3.18 or
higher.
• Upgrade the firmware in your 650 MDS Display/Logger from the YSI Website to Version 1.18 or
higher.
Note if your sonde was manufactured after June 1999, there is no need to return your existing sonde to YSI.
After carrying out the software upgrades described in detail in the instruction sheet shipped with the 6150
Probe, you will be able to simply install the ROX sensor in your optical port and begin taking readings. If
your sonde was manufactured prior to June 1999, then you should contact YSI Technical Support to
determine if it is compatible with the ROX sensor
Can I measure dissolved oxygen with both ROX Optical and Rapid Pulse Polarographic sensors in
the same sonde?
No. If you try to activate both the ROX and Rapid Pulse sensors in the sonde Sensor menu, only the last
sensor activated will be functional.
What are the key differences between the ROX Optical and Rapid Pulse DO sensors?
The key differences between the sensors are as follows:
