1 Module context
This module deals with significance and chemistry of dissolved oxygen measurement. Modules in which prior training is required to complete this module successfully and other available, related modules in this category are listed in the table below. While designing a training course, the relationship between this module and the others, would be maintained by keeping them close together in the syllabus and place them in a logical sequence. The actual selection of the topics and the depth of training would, of course, depend on the training needs of the participants, i.e. their knowledge level and skills performance upon the start of the course.
