Mini data logger for Temperature - testo 174-T
Model No: testo 174-T Part No: 0572 1560

The testo 174-T mini data logger measures and logs the air temperature and in storage rooms and offices continuously without interruption accurately and reliably.

  1. Display of current temperature value
  2. High data security
  3. Large display
  4. Fast data analysis and documentation on a PC
  5. Waterproof according to IP65
  6. Measurement data memory for 16,000 measurement values
  7. HACCP-compliant and certified according to EN 12830


If case of food and pharmaceutical products, the storage temperature of the goods should not exceed specific limit values under any circumstances. Testo 174T mini temperature data logger helps you comply with the specified temperature ranges. It records the temperature values reliably and thus ensures uninterrupted measurement data recording and documentation. 
 
This is what the testo174T mini temperature data logger offers  
 
You can save up to 16,000 readings with testo 174T mini temperature data logger securely. Because measurement data you have saved will not be lost even when the battery is empty or being replaced. This means a high level of data security is guaranteed. You can easily and quickly read the current temperature measuring value on its large display, along with any possible violations of limit values. The integrated NTC sensor stands for a high level of accuracy. Its large measuring range, from -30 to +70 °C; and its compact design make testo 174T temperature data logger a competent support for virtually every kind of temperature recording. 
 
Testo174T mini temperature data logger meets the requirements of EN 12830 and is HACCP-compliant, as well as having international HACCP certification, which means it is ideally suited for measurements in the food industry (e.g. for storage temperature measurement). Particularly practical: the data logger has water spray and jet Protection according to IP 65. This enables it to be left in the measuring location even when warehouses are being cleaned. The temperature data logger is also suitable for temperature control in refrigerators or cold stores, because it can be used at temperatures down to -30 °C. 
 
Programming and analysis with the mini temperature data logger  
 
You can choose between three software versions for programming and reading your data logger and for analyzing the measurement data on the PC: 
 
-   ComSoft Basic software –  available as a free download – for fast programming of the mini temperature data logger and easy data analysis 
 
-   ComSoft Professional software –  can also be ordered as an option – offers a variety of possibilities for detailed analysis of temperature readings 
 
-   ComSoftCFR 21 Part 11 software –  can also be ordered as an option – the best solution for special requirements according to CFR 21 Part 11 in the pharmaceutical          sector 

You need a USB interface for programming and reading the mini temperature data logger.
