# 174 H
The testo 174 H 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 to ensure that the property is being properly looked after by the tenants.
The testo 174 H mini data logger has built-in longlife sensors that can measure the temperature and humidity of the surrounding environment, a memory for up to 16 000 measurements and an easy-to-read display that shows the current reading as well as any breached thresholds.
Practical: The standard batteries (2x CR 2032) included in the scope of supply can be easily replaced by the user.
