The testo 174 data loggers are used for storing and reading out
individual readings and series of measurements.
Readings are measured and stored with the testo 174 and
transmitted to the PC via the interface, where they can be read out
and evaluated using the testo ComSoft software. The data logger
can also be programmed individually via the software.
Examples of applications
testo 174T is ideally suited for temperature measurement in in
refrigerators, freezers, cold rooms and cold shelves.
testo 174H monitors the climatic conditions, e.g. in warehouses,
offices and in the manufacturing sector.
