Manufacturer Description

Extech RH401 Digital Psychrometer + InfraRed Thermometer, Triple display with backlighting, Displays Air temp+RH+surface temp or Dew Point+RH+surface temp or Wet Bulb+RH+surface temp, Adjustable emissivity from 0.3 to 1.0

The RH401 is a Digital Psychrometer with a Built-in IR thermometer that allows quick non-contact surface temperature measurements. Displays air temperature, humidity and surface temperature or dew point, humidity and surface temperature or wet bulb, humidity and surface temperature on a triple LCD with backlighting. The meter calculates the temperature difference between IR surface temperature and dew point. Includes hard case and four AAA batteries.
