The FLIR EM54, based on hygrometer technology, identifies deviations from ambient relative humidity levels, which can cause static hazards at manufacturing sites and discomfort in homes and offices. This high-quality, easy-to-operate meter helps users quickly and accurately identify symptoms of clogged HVACR filters, duct leaks that reduce airflow, and overloaded systems. The FLIR EM54 is ideal for inspecting ducting, electrical motors, thermal equipment, and other system components in residential, commercial, and industrial facilities. Equipped with an external vane anemometer for wide-range, high-resolution air velocity measurements, it allows users to check air speed at duct inlets and outlets quickly and precisely. This allows for simplified duct airflow calculation and efficient troubleshooting. The meter includes a Type-K contact temperature probe to allow users to check electric motors and thermal equipment components for proper operating temperatures. It also calculates wet bulb and dew point temperature.

An intuitive set of function keys make it easy to use, and the backlit multi-function display makes it easy to read. It also features a MIN-MAX-AVG recording function and a programmable auto power off timer. The rugged, multi-purpose diagnostic tool comes with a three-year limited warranty.
