  FLIR EM54 HVAC/R Environmental Meter
The FLIR EM54 is designed for HVAC/R professionals who need a cost-effective, accurate, and reliable environmental meter. It is ideal for inspecting and troubleshooting ducting systems within residential, commercial, and industrial facilities.
The EM54 can help you verify that duct inlets and outlets have the specified volumetric flow – a prerequisite to an efficient functional system. Featuring humidity, wet bulb, and dew point functions, the EM54 can measure deviations from proper relative humidity levels.
Plus, the included contact temperature probe is useful to check electric motors and thermal equipment components for proper operating temperatures. All it takes is one tool to get all the environmental and equipment temperature measurements you need.
