    Practical expertise relating to temperature measurement with immersion thermometers

    Immersion thermometers from Testo are specifically designed for measuring the temperature in liquids, pastes and semi-solid media such as meat, fish or dough. Here, no distinction is made between immersion thermometers and penetration thermometers, because the probe tip is optimized for media ranging from liquid through to semi-solid. However, depending on the application, different performance characteristics are required in the temperature measurement.

    Prevent measurement errors with your thermometer for immersion

    One of the most common application errors when it comes to temperature measurement is impatience. Why is that? Because your immersion thermometer requires a sufficient acclimatization time. If the temperature probe and measurement object are at different temperatures, the measurement results are falsified because the actual temperature is not measured. If, for example, the probe is colder than the measurement object, it extracts the heat – and therefore energy too. You can easily prevent this by observing the so-called t99 time and two rules of thumb:
