The testo 175 T2 temperature data logger has an internal sensor and a connection for an external temperature probe. This means it is ideally suited for use when you do not just want to record the indoor air temperature, but also want to carry out another temperature check (e.g. a core temperature spot check).
This is practical when storing and processing food, amongst other things: measure the ambient conditions of your goods in storage areas and cold stores and at the same time check the temperature level of the goods themselves – for example with a penetration probe (optional). Temperature control in the gaps in the packages is also possible. The measurement results from both channels are securely stored in your temperature data logger.
