It is common for temperature and humidity measuring devices to be used in commercial and industrial settings so that they can monitor the changes in temperature and humidity levels. There is a wide range of applications that can be served using bimetal and digital thermometers. These include applications in indoor and outdoor settings, heating and cooling systems, and chemical processing. In remote areas, wireless thermometers and humidity meters are used to monitor the temperature data and to measure the humidity levels. For accurate and precise readings to be obtained in hazardous or hard-to-reach areas, infrared thermometers, cameras, and thermal imagers may be used.
