The FLIR EM57 is a thermo-hygrometer for HVAC technicians, building inspectors, facility professionals, and restoration and remediation specialists who need to understand temperature and humidity conditions in buildings. It brings air temperature, relative humidity, dew point, and wet-bulb readings into one instrument, helping users assess comfort, building performance, and indoor air quality while MeterLink streams readings wirelessly for reporting.
Why the FLIR EM57 Fits Building Diagnostics
-
ASSESS TEMPERATURE AND HUMIDITY TOGETHER
Building conditions rarely make sense from temperature alone. The EM57 measures air temperature and relative humidity together, giving HVAC and facilities teams the paired information needed to investigate comfort complaints, ventilation performance, and changing indoor conditions.
-
CHECK DEW POINT DURING MOISTURE INVESTIGATIONS
Dew point helps an inspector judge when air conditions may allow condensation on colder building surfaces. Used alongside a suitable FLIR moisture meter, the EM57 adds ambient context without duplicating the moisture meter's role in locating or assessing material moisture.
-
USE WET-BULB READINGS FOR HVAC WORK
Wet-bulb measurement supports psychrometric checks when technicians are evaluating air-conditioning and ventilation performance. Having wet bulb, dew point, air temperature, and relative humidity available on the same instrument keeps ambient-condition checks focused and practical.
-
STREAM READINGS WITH METERLINK
MeterLink sends readings wirelessly for reporting, reducing the need to copy measurements manually during a survey. This supports clearer records when technicians need to connect observed building conditions with the measurements taken at the time.
-
READ RESULTS IN WORKING AREAS
The backlit LCD uses multi-function indicators so technicians can review measurements in plant rooms, ceiling spaces, and other building-service locations. The straightforward display keeps attention on the survey rather than on a complicated interface.
-
MAINTAIN THE SENSING COMPONENT
The supplied MR13 temperature and relative humidity sensor is replaceable, supporting continued field use of the instrument. FLIR recommends a calibration cycle of once per year, giving teams a clear basis for planning instrument control.

Frequently asked questions
What does the FLIR EM57 measure?
The FLIR EM57 measures air temperature and relative humidity and provides dew-point and wet-bulb readings. This combination gives HVAC technicians and building professionals ambient-condition information for comfort, indoor air quality, building-performance, and condensation-related investigations.
How does the EM57 complement a FLIR moisture meter?
The FLIR EM57 is a thermo-hygrometer for measuring ambient air conditions; it does not duplicate a moisture meter's role in assessing material moisture. Used with a FLIR MR60, MR160, MR176, MR265, or MR277, the EM57 adds temperature, relative humidity, dew-point, and wet-bulb context to a wider moisture investigation.
What is MeterLink used for on the FLIR EM57?
MeterLink on the FLIR EM57 streams readings wirelessly for reporting. This helps technicians retain measured ambient conditions as part of their survey record rather than relying on manually copied values.
Is the temperature and humidity sensor replaceable?
Yes. The FLIR EM57 includes an MR13 replaceable temperature and relative humidity sensor, and FLIR recommends calibration once per year.
What is supplied with the FLIR EM57?
The FLIR EM57 is supplied with the MR13 replaceable temperature and relative humidity sensor, a Quick Start Guide, three AAA alkaline batteries, a carrying pouch, and a lanyard. GoThermal supplies and supports the instrument in South Africa.
