Excerpt from A Calibration Model for Screen-Caged Peltier Thermocouple PsychrometersSerious problems arise when attempting to relate lab oratory calibrations made under isothermal conditions to field data collected in unstable thermal environments.Although the errors caused by temperature gradients have long been recognized (rawlins and Dalton the normal practice has been to ignore them. Not until Wiebe and others (1977) and Wiebe and Brown (1979) quantified the errors caused by temperature gradients could suggestions be made of how to avoid them, or otherwise minimize their effects. They defined the magnitudes of temperature gradient errors and identified various flaws in psychrometer design that aggravate them. Michel (1979) subsequently studied temperature gradient effects on psychrometer calibration over narrow ranges of micro volts and temperatures.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
