Greenspan Dissolved Oxygen Sensors DO100 DO1200 and DO300
Greenspan Dissolved Oxygen Sensors utilise the patented CSIRO/Greenspan developed diffusion cell, which is pervious to oxgen flow. Includes temperature output and DO results are output in either PPM or the option of %SAT. All components feature low power consumption for continuous long-term performance.
