Many research tasks in the laboratory require exact temperature control, but advertising claims such as extremely fast or high-cooling capacity make choosing a circulator difficult. These phrases are not very meaningful and do not permit any objective assessment.
It is essential for the user to be able to make meaningful comparisons. DIN 12876 defines various characteristics and measurement methods for this purpose. These are used as an orientation for heating circulators and cryostats. Characteristics recorded in this manner facilitate a reliable comparison of the performance.
