Example Sentences:
(1) This paper describes the production and calibration of a miniature psychrometer treated with a specially developed porous coating.
(2) With the help of a psychrometer-normogramme the absolute humidity is determined from the data of the wet and both the dry thermometers.
(3) Procedures that would decrease this discrepancy even further were pinpointed, and advantages of using the miniature psychrometer were assessed.
(4) A precision humidity generator was developed for calibrating the psychrometer.
(5) Maximum difference between minihygrometer and August's psychrometer parameters reaches 0.5%.
(6) Existing psychrometers of small dimensions cannot provide accurate long-term measurements of water-vapor pressure without frequent maintenance and recalibration.
