Abstract

An aquatic environment water parameter testing system and related methods and chemical indicator elements. The aquatic environment water parameter testing system includes an electronics portion having an optical reader element and a sample chamber portion. Conductivity and/or temperature may be utilized to calibrate readings by the optical reader element. A system may optionally have a sample chamber portion having a chemical indicator element which may be removably connected. A chemical indicator element may include an information storage and communication element used, in part, to provide identification of a chemical indicator of the chemical indicator element.
