Uncertainly Analysis of Two Types of Humidity Sensors by a Humidity Generator with a Divided-Flow System
Humidity measurement is an important technique for the agricultural, foods, pharmaceuticals, and chemical industries. For the sake of convenience, electrical relative humidity (RH) sensors have been widely used. These sensors need to be calibrated to ensure their accuracy and the uncertainty measurement of these sensors has become a major concern. In this study, a self-made divided-flow generat...
متن کاملEffect of temperature and humidity in the Schirmer tear test.
THE Schirmer I tear test developed and standardized by Halberg and Berens, New York City (Contactisol Inc. Lindenhurst, N.Y.) is a useful screening procedure for keratoconjunctivitis sicca in large numbers of patients suffering from various connective tissue disorders. When all the patients attending a centre for rheumatic diseases were subjected to this test it was noted that a surprisingly hi...
متن کاملTemperature, humidity and mucus flow in the intubated trachea.
Mucus flow rates were measured in the intact trachea of anaesthetized dogs, using a radioactive tracer technique. Measurements were made before intubation, and after intubation at inspired air temperatures of 32, 37 and 42°C, with a constant inspired water vapour content of 33 mg/1.; and again at each temperature with a relative humidity of 75%. No significant difference in mucus flow rate was ...
متن کاملLow temperature formation Silver-Copper alloy nanoparticles using hydrogen plasma treatment for fabrication of humidity sensor
In this paper, a novel method of producing bi-metallic alloy nanoparticles at low temperatures using hydrogen bombardment of thin films, deposited on glass substrates, is introduced. Optical and morphological characteristics of the nanoparticles were extensively studied for various conditions of plasma treatment, such as plasma power density, temperature, duration of hydrogen bombardment, thick...
