Orion 3-Star pH DO Meter

It displays DO concentration or percent DO saturation and also offers a full complement of GLP related features including a 21 CFR Part 11 software option. SMART STABILITYTM and SMART AVERAGINGTM functions and a quick start guide located on the back of the unit make operation in the field even easier.

The unit offers automatic barometric pressure compensation, salinity correction and enhanced stability indicators. It can store up to 750 data logs and has the ability to turn off the data log.

Additional features include:

  • Comfortable handling
  • Backlit LCD display
  • Up to 10 methods can be stored
  • Password protection on methods
  • Optional USB outputs
  • Uses polarographic DO probe
  • IP67 waterproof rating (may be immersed for one hour with no water incursion)
