Pond Boss Forums GENERAL QUESTIONS Water chemistry DO meter recommendations

Thanks for the help, I did a little checking and found that there is a lot of things to consider here. Including the type of sensors wanted, Galvonic or Polargraphic (?). One of the websites listed the YSI Pro ODO as being discontinued and replaced with a unit called the Pro SOLO. I did find a lower priced model, the YSI DO200ACC-10 Dissolved Oxygen Meter kit but wonder what I am missing in the cheaper model.
