Water and Wastewater Disinfection
Course Pack: Specialized Chemistry & Field Monitoring
Thermometers and Other Measuring Devices
Course Description
This module provides a practical overview of thermometers and temperature measurement tools used in water treatment and utility operations. Learners will explore different types of thermometers, including bimetallic and fluid-expansion designs, along with proper calibration methods and accuracy verification practices.
The course covers essential thermometer applications, including temperature monitoring in laboratory, tank, autoclave, and field environments. Participants will learn about NIST-aligned calibration principles, mercury hazard awareness, safe handling procedures, and common factors that affect measurement reliability. Through practical examples, operators will understand thermometer limitations, proper usage techniques, and the importance of accurate temperature measurements for effective water system operations and process control.
Learning Objectives
1) Differentiate thermometer types
2) Recognize mercury hazards and alternatives
