Anyone whose job requires calculating humidity levels will appreciate the Extech Hygro-Psychrometer. This handheld instrument measures relative humidity in 30 seconds and also measures dew point, wet bulb, temperature, and water vapor levels (grams per kilogram and grains per pound). This utility tool will save maximum and minimum values until the memory is cleared, and it includes a data-hold button for quickly fluctuating measurements. Complete with a carrying case and a 9V battery.
