Orion 4-Star pH ISE DO Meter

There is a convenient quick start guide located on the back on the meter to make operation in the field easy.

Reliable measurement of pH and ionic concentrations, is offered by the meter, and a full complement of GLP related features including a 21 CFR Part 11 software option. 1 to 5 point manual or automatic calibration for pH and direct ion measurement ensures accuracy.

The measurement process is simplified with SMART STABILITYTM?and SMART AVERAGINGTM. You can log and store up to 10 setup parameters and calibrations.

Additional features:

  • Manual ISE calibration with 1 to 5 calibration points
  • Self diagnostic tests
  • IP67 waterproof rating (may be immersed for up to one hour with no water incursion)
  • Comfortable handling
  • Stores up to 10 methods
  • Password protection
