H814 Humidity Measurement Bench
Penjelasan Produk
A self contained bench top unit comprising a number of different types of humidity meters and a small air duct with fan for variation of air velocity together with a simple air velocity meter.
Students can investigate the use of the standard wet and dry bulb whirling hygrometer in the normal way. Using the air duct the effect of air velocity on wet bulb temperature can be investigated. The wet and dry bulb method can be compared with a direct reading psychrometer, hair hygrometer , a synthetic material hygrometer and an electronic humidity sensor.
All of the measured parameters can be related using the large encapsulated psychrometric chart that is supplied and by detailed calculation.
