2. Introduction

Thank you for selecting the FLIR EM54 Environmental Meter. The EM54 measures Air
Temperature, Type-K Temperature, Relative Humidity, and Air Velocity and calculates
Dew Point/Wet Bulb Temperature and Airflow (volume). Visit
www.flir.com/testwarranty to read the 3-Year Limited Warranty document and to
register your product to receive a free 1-year warranty extension.

Features

• Dual reading, backlit multi-function display

• Measures air temperature and relative humidity via built-in temperature and

relative humidity sensors

• Measures air velocity and Type-K temperature using remote probes

• Side compartment with micro USB port for vane anemometer connection and sub-

miniature jack for Type-K thermocouple probe connection

• Calculates Wet Bulb and Dew Point temperature

• Calculates airflow (CFM/CMM air volume) in air ducts using an air velocity

measurement and a user-programmed air duct area value

• Selectable units of measure

• MIN-MAX-AVG recording

• Programmable Auto Power OFF (APO) timer

• Low battery indication

• Setup mode for changing default settings and for entering area measurements for

airflow measurements
