August 7, 2011
The Vaisala HM40 from Cole-Parmer, Vernon Hills, IL, is a pocket-sized tool that lets you spot check humidity and temperature. The device incorporates a HUMICAP humidity and temperature sensor that offers high accuracy, long-term stability, negligible hysteresis, and insensitivity to dust and most chemicals. The meter can display RH, temperature, dew point, wet bulb, absolute humidity, mixing ratio, and enthalpy on the large graphic display; a graph shows when the measurement is stabilized.
