Thermometers & Temperature Measurements Model TH 092
Thermometers & Temperature Measurements Model TH 092
* Experimental introduction to temperature measurement: methods, areas of application, characteristics
* Clearly laid out unit primarily for laboratory experiments, also suitable for demonstration purposes
Item Description
Sci-tech Thermometers & Temperature Measurement Apparatus Model TH-092 experimental set-up covers the full range of temperature measurement methods. As well as non-electrical measuring methods, such as gas- and liquid-filled thermometers and bimetallic thermometers, all typical electric measuring methods are covered in the experiments. The electrically measured temperatures are displayed directly on programmable digital displays. A temperature-proportionate output voltage signal (0…10V) is accessible from lab jacks, enabling temperature characteristics to be recorded with, for example, a plotter. For measuring the relative air humidity a psychrometer with two thermometers is available, one of the thermometers measures the dry bulb. The wet bulb thermometer is covered in a wet cotton cloth and measures the evaporative cooling. The temperature difference allows the relative air humidity to be determined.
