Before there was the thermometer, there was the earlier and closely related thermoscope, best described as a thermometer without a scale a thermoscope only showed the differences in temperatures, for example, it could show something was getting hotter. Thermodynamics lab introduction: thermodynamics is the study of energy which can exist in many forms, such as heat, light, chemical energy, and electrical energy the variables that thermodynamics can be used to define include temperature, internal energy, entropy, and pressure. Using a thermometer we can locally measure the body temperature at the point of contact typically we are interested in the 'core temperature' of the body, this is why we try to put the thermometer as 'deep' inside the body as possible (eg in an armpit or ear). The innovo thermometer is all about ease of use: inserting the probe inside the ear or on the forehead, pressing f2 or f1 for ear and forehead respectively and reading the temperature on the digital screen, which is backlit to ensure nighttime legibility.
