The silent guardians
of the cold chain.
Testo data loggers for product integrity in pharma and industry.
Cold chains fail quietly. When a door remains open too long, a transport is delayed, or an environmental condition moves outside its defined limits – often unnoticed until product integrity or compliance is compromised. Testo data loggers operate as the silent guardians of the cold chain. Working reliably in the background, they record critical parameters, document deviations and create transparency across production, storage and transport – providing the data foundation needed to support product integrity in pharmaceutical and industrial applications.

From short-term transport documentation to long-term stationary monitoring, Testo data logger series support different ways of recording and evaluating measurement data across the cold chain.
testo 174 family
Mobile and stationary data loggers. Ready for use in transport and storage. Frequent readout via USB or Bluetooth.
testo 175 family
Stationary data loggers for long term monitoring. Designed for storerooms and refrigerated units.
testo 176 family
Professional stationary data loggers. Designed for laboratories, industrial environments and production.
testo 184 family
Mobile data loggers for transport monitoring. Data and reports can be read directly from the logger.
Calibration and validation you can rely on
Reliable data is essential in pharmaceutical and industrial environments, where quality, safety, and compliance are critical. With calibration and validation services from Testo, you ensure that your measuring instruments deliver accurate and traceable results throughout their entire service life.
From factory and accredited calibration to application-specific validation, Testo supports users with standardized processes, comprehensive documentation, and expert know-how. This helps you meet regulatory requirements, reduce measurement uncertainty, and maintain confidence in your measurement processes – even under demanding operating conditions.
Centralized monitoring for
controlled environments
When conditions define quality, continuous visibility is essential. testo Saveris 1 records temperature, humidity and other critical parameters across pharmaceutical storage, production and cleanroom environments.
With real-time insight, secure documentation and intelligent alarms, the system supports confident decisions and reduces manual effort in everyday operations.
