The  Mini temperature data logger Testo 174T is an ideal data logger for the continuous monitoring of temperatures.

Because storage temperatures should never exceed specific limit values, the 174T records the temperatures values and alerts when thresholds have been exceeded.

  • High accuracy NTC thermistor sensor for reliable data
  • Easy to read large display that shows current reading and exceeded measurement limits
  • IP65 protection class
  • HACCP compliant


Monitoring and documentation of the temperature in cold rooms

Many foods and drugs have to be stored within a specific cold temperature range. This can be done in individual cooled store rooms, but also in specialised cold stores or cold warehouses with high-rack facilities. The temperature must be continuously documented in all these cold storage facilities, because strict rules apply to quality management in both the food and drugs industries.

Data loggers are usually installed at the so-called critical control points (CCPs) of the cold room, in order to identify any possible temperature deviations and to introduce appropriate countermeasures. Critical points are for instance doors or passages through to other temperature areas within a warehouse.

Monitoring and documentation of transport temperature

For all goods which react sensitively to temperature fluctuations or have to be stored within a predefined temperature range, uninterrupted measurement data recording and documentation play a major role.

Incorrect temperature conditions during transport can lead to major losses of quality, including the total loss of value of the products that require monitoring.

Using a data logger, shipments can be checked for compliance with the specified temperature ranges and the data can then be read, analysed and archived by means of special software.
