FLIR EM57 Thermo-Hygrometer with Meterlink
The FLIR EM57 Thermo-Hygrometer with Meterlink gives HVAC professionals a quick way to check indoor temperature, relative humidity and related environmental conditions. It measures air temperature and humidity while automatically calculating dew point and wet bulb temperature. These readings support checks of occupant comfort, HVAC system performance and indoor air quality.
Instant dew point and wet bulb values help users assess condensation risk and moisture conditions before they lead to mould growth, equipment problems or poor indoor comfort. The instrument is suited to HVAC servicing, commissioning and troubleshooting, where fast environmental checks can help confirm system performance. Its backlit LCD also provides clear access to readings and multi-function indicators during routine work.
The FLIR EM57 Thermo-Hygrometer with Meterlink also supports Bluetooth connectivity with the FLIR Meterlink app on a compatible mobile device. Users can capture readings wirelessly, compare measurement trends and generate reports during inspections and maintenance work. With more than 100 hours of battery life, a 2 m drop-tested construction and an IP40 enclosure, it is designed for regular professional use.
