Demodectic Mange in Dogs. Demodicosis in Dogs. Mange (demodicosis) is an inflammatory disease in dogs caused by various types of the Demodex mite. When the number of mites inhabiting the hair follicles and skin of the dog become exorbitant, it can lead to skin lesions, genetic disorders, problems with the immune system and hair loss (alopecia).
There are numerous sensors available for temperature measurement under the name thermal sensors. Popular ones are the thermistor, thermocouple, RTD. Diodes can be used to sense temperature due to the change in their forward voltage with change in temperature. One of the advantage of using diodes is they have a nearly linear relationship between temperature and voltage applied.
Digital thermometers. These thermometers use electronic heat sensors to record body temperature. They can be used in the rectum (rectal), mouth (oral) or armpit (axillary). Armpit temperatures are typically the least accurate of the three. Digital ear thermometers (tympanic membrane). These thermometers use an infrared ray to measure the temperature inside the ear canal. Keep in mind that earwax or a small, curved ear canal can interfere with the accuracy of an ear thermometer temperature. Temporal artery thermometers. These thermometers use an infrared scanner to measure the temperature of the temporal artery in the forehead. This type of thermometer can be used even while a child is asleep. Digital pacifier thermometers and fever strips are not recommended.
