A temperature log is a document in which information about temperatures is maintained. The log usually consists of temperature readings taken at set intervals over a given period of time. Logging is used in a number of different contexts, ranging from meteorology to fertility treatment, and there are a number of utilities available to make it very easy to set up and maintain a temperature log.
A typical temperature log includes space in each entry to record the temperature, the time the temperature was taken, the date, and any observations which may be relevant. The log may also include a space for a note to indicate who took a temperature measurement, and what kind of equipment was used for the reading.
While temperature logging on paper is still done in some regions of the world, a temperature log is often digital. There are some distinct advantages to logging digitally. For one thing, digital equipment can be set up to log automatically, reducing the rate of human error and streamlining the logging process. In addition, an electronic temperature log can be easily shared, transported, or transmitted, in contrast with a hard copy. Digital logs can also be fed into programs which do things like preparing charts and graphs with the data.
Weather agencies commonly keep temperature logs for a number of locations, with temperatures being taken several times a day year round. These logs are used to provide general temperature data, and for the purpose of weather forecasting. Information about temperatures can be useful for people who work outdoors, and for people like farmers and gardeners, for whom prevailing temperatures are a concern when it comes to scheduling planting.
Temperature logging is also common in scientific experiments where temperature changes are likely to be observed. The experimenter charts all observable changes, collecting data which can be used later when analyzing the experiment and exploring the experimental outcome. A temperature log can also be used as a food safety tool, with people verifying temperatures on a regular basis to confirm that food is being held in a safe range, and to demonstrate proof that someone is checking temperatures.
In the medical field, temperature logs are usually kept on hospitalized patients and patients in surgery, as changes in temperature can be indicators of health. People tracking fertility at home may opt to use temperature logging as one tool to keep track of their cycles.
