A miniature gravity-fed thermocouple psychrometer was constructed and tested over a wide range of humidities and flow rates. The unit gave accurate wet bulb depression in 6-mm flow tubes through an acrylic plastic block with a minimum flow rate of only 0.06 m/sec at 35% RH, and of only 0.09 m/sec at 11% RH.
The psychrometer also agreed exactly with a standard psychrcmeter (Assmann type) in open air without forced ventilation or radiation shielding.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
