We have been using Onset data loggers and HOBO software for many years. An excellent, well-engineered, well-supported, and attractively priced product line. Accurate, reliable, consistent results and logs. We are a multidiscipline consulting engineering firm and can vouch for the usefulness of these loggers in the field.
