The testo 176 T1 offers protection from adverse conditions due to its robust metal housing. A highly accurate Pt100 sensor in the interior measures the temperature. The testo 176 T1 is, for example, excellently suitable for the recording of temperature data over long periods in refrigerated and deep-feeze rooms. The metal housing is resistant to mechanical influences, e.g. knocks from a palete on a forklift. Like all Testo data loggers for applications in the food sector, the testo 176 T1 is tested according to DIN EN 12830 by the ATP testing section of the TÜV Süd.
