This professional hygrometer features fast-response relative humidity and temperature sensors with exceptional precision. Others charge considerably more for ±2% RH accuracy. The well-designed DT-3321 feels good in the hand. It's compact, lightweight and easier-to-use than other hygrometers, pyschrometers and humidity meters.

For more advanced measurements select display units for dew point, wet bulb, and mixing ratio using the side buttons. With a dual display you can measure humidity (relative or absolute) and simultaneously display dew point, wet bulb, or ambient temperature. A large backlit display gives you a convenient display of all readings even in darker locations.

The DT-3321 includes HOLD and MIN/MAX functions. The 10 minute auto-off saves battery life. Disable the auto-off for continuous measurement. You won't find a more accurate humidity meter for this price. Competing units sell for $170 to $250. The DT-3321 is only $99.00 including the carrying case. If humidity matters to your work, you'll be glad you chose the DT-3321.
