Just received. I bought it to measure wet bulb temperature for use in HVAC applications. This instrument measures temperature and humidity, and then calculates the wet-bulb temperature using a complex (built-in) algorithm. I didn't want to carry around a computer with a wet-bulb temperature chart. I have not compared this device's measurements to any other standard, but I have no reason to believe it is not accurate. Seems good value for what I paid. Delivery was promised 2 days.
