EM54 by Flir
The multi-purpose EM54 environmental meter for heating, ventilation, air conditioning, and refrigeration (HVAC/R) measurements is based on hygrometer technology. It identifies deviations from ambient relative humidity levels, which can cause static hazards at manufacturing sites and discomfort. The high-quality meter helps users identify symptoms of clogged HVAC/R filters, duct leaks that reduce airflow, and overloaded systems. The meter is designed for inspecting ducting, electrical motors, thermal equipment and other system components.
