Flir EM57 Thermo-Hygrometer, Humidity Dew Point Wet Bulb Meter, Meterlink -20 to 60 C at +/-0.5 C, 0 100% RH +/-2%, replaceable MR13 sensor, 100+ hour battery, IP40, 2 m drop tested

FOUR READINGS, NOT JUST TEMPERATURE: Air temperature, relative humidity, dew point and wet bulb are all measured across -20 C to 60 C (-4 F to 140 F), so you can assess occupant comfort, indoor air quality and HVAC performance from one meter ACCURACY YOU CAN PUT IN A REPORT: Air temperature, dew point and wet bulb carry +/-0.5 C basic accuracy and relative humidity 0 to 100% carries +/-2% basic accuracy, with 0.1 measuring resolution and annual calibration recommended SPOT CONDENSATION, MOISTURE AND MOLD RISK EARLY: Dew point and wet bulb readings reveal condensation risk, moisture loading and latent load conditions that can lead to mold growth or building envelope problems before damage becomes visible FIELD-REPLACEABLE MR13 SENSOR: The MR13 temperature and relative humidity sensor is user replaceable, so a damaged or drifting sensor can be swapped on site instead of taking the meter out of service. One MR13 sensor is included METERLINK APP LOGGING AND JOBSITE DURABILITY: Bluetooth sends readings to the Flir Meterlink app to capture, compare trends and share findings. Backlit LCD, over 100 hours on 3 AAA batteries, IP40, 2 m drop tested, limited 3-year warranty
