Extech RH401
Digital Psychrometer + InfraRed Thermometer
The Extech RH401 is a Digital Psychrometer with a built in IR Thermometer that allows for quick, non contact surface temperature measurements. It displays air temperature, humidity, surface temperature or dew point, and wet bulb, all on a triple LCD with backlighting. The IR thermometer features adjustable emissivity and a spot to distance ratio of 8:1. The meter calculates temperature difference between IR surface temperature and dew point. Other features include data hold, programmable auto power off, and a retractable probe that protects the sensors when the meter is not in use. Includes hard case and four AAA batteries.
