The testo 174 H mini data logger allows you to monitor temperature and humidity sensitive goods– including foods, archives or metal parts that are susceptible to surface rust – or carry out discreet humidity checks in buildings.
The mini data logger has built-in long life sensors that can measure the temperature and humidity of the surrounding environment, a memory for upto 16,000 measurements and an easy-to-read display that shows the current reading as well as any breached thresholds.
The standard batteries (2x CR 2032) included with the logger can be easily replaced by the user.
