Humidity Measurement Bench

  A self contained unit with two electronic humidity sensors and three analogue sensors. These include direct reading psychrometer, hair hygrometer, synthetic material hygrometer, capacitive sensor hygrometer with temperature measurement, and whirling (centrifugal) wet and dry bulb sensor. An air duct and fan and simple air velocity meter allows the effect of air velocity to be investigated. An optional digital temperature wet and dry bulb sensor is available. An optional 35 channel data acquisition system and software is available for use with the optional digital temperature wet and dry bulb sensor and any other compatible transducers.
