Measurement procedure and accuracy
Recording can be started either when the battery is inserted, or the device can wait for a long time (months) for a trigger condition: a temperature rise above a defined threshold or the application of a magnet.
During the measurement, it is possible to add a time stamp to the recording by attaching a magnet, for example to mark the moment when the instrument is removed from the container, etc.
The advantage of the instrument is its high accuracy and resolution: sensor accuracy +- 0.25 °C without further calibration with a resolution of 0.0078 °C. This fine resolution makes it possible to detect, for example, the effect of movement of people in the room when measuring the air temperature. The temperature sensor used is factory calibrated (NIST traceable).
Use for measuring in a wash bath
One typical use of the TBUG datalogger is to record the temperature progression in the washing machine during the wash cycle, for example to document the correct execution of the balancing process for hygiene reasons. Simply place the data logger in a washing machine (whether a conventional automatic or industrial washing machine) and remove it at the end of the washing cycle. If the trigger condition is set correctly to e.g. 40 °C, the measurement starts when the device detects the water heating of the washing bath, and the measurement ends after the set time (e.g. after two hours).
In this way, we can perform several washing cycles and measurements, which will be individually recorded in the memory of the device, including the time of the start of the measurement. Then we can read them using the application in the computer and we can display the temperature graphs, or export the data to a format that we can work with further, e.g. in MS Excel.
