Summary
The subject is aimed on metrology knowledge improvement in the field of the heat-technical quantities measurement. It deals with the temperature, pressure, humidity, volume and mass flow measurement process and gas analysis. The main purpose is to demonstrate the measurement methods used in the laboratory as well as in the operational conditions.

Way of continuous check of knowledge in the course of semester
During the semester students should pass through 10 labs in order to verify the theoretical knowledge in practice.
Before beginning of each laboratory exercise, the lector is authorized to check the student's knowledge which is necessary to accomplish the particular exercise.
To fulfil exercises requirements student has to elaborate all of the lab exercises reports.
Student has to pass the final oral exam to successfully accomplish the course.
