FLIR EM54 Environmental Meter (Air Velocity/Flow, Temperature, Humidity)

One tool provides all the environmental measurements you need

The FLIR EM54 is ideal for inspecting and troubleshooting HVAC/R ducting systems within residential, commercial, and industrial facilities. This meter 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 Type-K contact temperature probe is useful to check electric motors and thermal equipment components for proper operating temperatures.

ACCURATE AND RELIABLEReceive high-quality data consistently, and work without interruption. Using the tripod, place the meter away from objects that may influence relative humidity measurements.

INSPECT AND TROUBLESHOOT EFFICIENTLYWork on a wide range of systems more efficiently using the contact temperature probe and wet bulb/dew point calculations.

EASY TO USEIntuitively operate this simple, ergonomic meter with a backlit display, a ‘hold’ function that freezes readings, and well-marked function keys.
