Temperature data loggers are used for temperature and humidity monitoring and are above all employed in the industrial sector, where temperature and humidity play a major role. In this respect, a distinction is made between single-use instruments and long-term monitoring instruments.

The single-use instruments are mainly used to record values within a short period of time. However, it is important to be able to evaluate humidity and temperature over a long period of time, particularly in production.

When purchasing a data logger for temperature, there are various factors that have a role to play:

• high level of accuracy
• effective repeatability for test purposes
• long rechargeable battery service life
• low follow-on costs
• very good software
