Thank you for purchasing the YSI Professional Optical Biochemical Oxygen
Demand (ProOBOD) probe. The ProOBOD is designed for use with a YSI
ProODO® instrument. The probe will not work with any other YSI instrument.
This manual provides information on the ProOBOD probe only. For more
detailed instructions on how to operate the ProODO instrument, please refer to
the ProODO User Manual (www.ysi.com/ProODO).
The ProOBOD is designed to fit in a standard 300 ml BOD bottle as well as other
international BOD bottles, depending on the version of the probe. YSI offers
two probe versions:
ProOBOD USA (Japan), YSI item number 626400 - This probe fits in •
standard USA and Japanese style BOD bottles. A power supply for
USA and Japanese style AC outlets is included.
ProOBOD International, YSI item number 626401 - This probe fits •
in standard BOD bottles used outside the USA and Japan. A funnel
adapter for fitting in standard Uk BOD bottles and a switching power
supply with 3 international outlet adapters are also included.
The ProOBOD sensor measures dissolved oxygen in water using lifetime
luminescence technology and uses a digital signal to send information between
the instrument and probe. The probe features a stirrer and motor to aid in
sample movement, to keep solids from settling at the bottom of the sample bottle,
and to speed up the response of the sensor. key advantages of the ProOBOD’s
use of optical technology for DO measurement over traditional electrochemical
methods include the elimination of sensor flow dependence and sensor warm-
up time, greater stability, the ability to zero the sensor for more accurate
measurements at low dissolved oxygen levels, and the elimination of frequent
membrane/electrolyte changes and electrode servicing.
For more information on the ProODO instrument and product specification,
please visit www.ysi.com/ProODO or contact Technical Support at 800-897-
4151 (+1 937 767-7241).
Reading the entire manual before use is recommended for an overall
understanding of the probe’s features.
Important: The ProOBOD is designed for laboratory use, not
field use. It is not waterproof and should never be immersed
in a sample past the taper on the stem of the probe.
