A dissolved oxygen probe is available that can be used directly with a 
stardard pH meter, a strip chart recorder, or can plug directly into the 
serial port of a PC to monitor and record oxygen levels.  The probe 
totally eliminates the need of an expensive dissolved oxygen meter.  

The DO probe comes in several versions including a field model for 
ponds, rivers, and lakes with cable lengths up to 100 ft., a BOD model, 
a micro probe for measuring small biological and environmental samples, 
and  flow through model for measuring flowing streams in biotechnology, 
HPLC etc.
