The practice of measuring light, airflow and pressure has become a common practice which has developed from the need of making sure that employees are operating in safe working conditions. Airflow meters are basically mass flow meters, as they determine the air velocity and air pressure by measuring the mass flow of air. Light can be properly measured with the use of Light Meter.
A range of hand-held meters are available to cover a number of different requirements in light, airflow and pressure, some with logging capabilities. Some climate meters are multifunction meters capable of multiple measurements.
