A test instrument is used for testing, adjusting, and balancing (TAB) and maintenance activities of the HVAC system. Parameters such as airflow, quality, electrical connection and integration with other systems, temperature, and humidity conditions are measured using HVAC test instruments. These test instruments include clamp meters and anemometers, among others. Increasing occupant comfort at the lowest energy cost is the primary objective of HVAC TAB activities.
One trend in the market is building automation systems. Building automation systems (BAS) that control and monitor HVAC and other facilities of a given building are improved by embedding them with computing and digital communication tools that allow them to enhance energy efficiency. The number of integrated BAS installations has increased owing to the rise in the number
