What are the Different Types of Calibration Profiles?

Calibrations can be linear, logarithmic, single-line, and multi-line fit. 

The calibration method used depends on the method required.

pH and Color calibrations are linear, single-line fit calibrations.

Conductivity and Turbidity calibrations are multi-line, linear type calibrations.

ISE (Fluoride, Chloride, Ammonia, etc.) use a logarithmic multi-line calibration type.
