THERMO HYGROMETER CALIBRATION SERVICES IN CHENNAI. "A hygrometer is an instrument that can range from something that is really basic in design, such as a psychrometer or the hair hygrometer, on up to more detailed instruments, like a cooled mirror dew point hygrometer, which actually measures humidity using the condensation temperature. When it comes to calibrating equipment of this type and purpose it seems many manufacturers do a single point or two point calibration. The calibration report includes a simple equation for each calibration point that gives the user a correction to the hydrometer reading that accounts for the surface tension of the liquid in which the hydrometer is used. The calibration of the dewpoint hygrometer as described and illustrated, will be a 3 point sample calibration at 20, 50, & 80% RH at a test temperature of 25 °C. To calibrate them properly it usually takes me a couple of days. This video is going to demonstrate how to properly calibrate a brand new digital hygrometer using the salt test.Brought to you by http://www.goodfellascigars. It may also be used to calibrate chilled-mirror hygrometers measuring dew/frost-point temperature when an additional pressure measurement is made at the inlet of the hygrometer. Description.
