testo 190 T4 CFR temperature data logger – with long and flexible dual probe

Producer:
SKU: TESTO-0572-1904 Category:
  • Long, flexible dual probe for accurate temperature measurement in sterilization, freeze-drying applications
  • The testo 190 T4 is used to determine the acclimatization time between the internal and external temperatures.
  • Durable, sturdy, guaranteed waterproof 100% even after battery replacement
  • Changing the battery takes only seconds, saving time and increasing work efficiency.
  • Configure and read out up to 8 testo 190 CFR data loggers simultaneously with the multi-purpose case

The testo 190 temperature logger is specially designed for the pharmaceutical industry. It is suitable for monitoring the temperature in autoclaves, containers, liquids or on surfaces, for example on plates in freeze-drying systems.

Validation of sterilisation and freeze-drying processes, which must comply with the requirements of CFR 21 part 11, is a key element of quality assurance in the pharmaceutical industry. The truly reliable and robust testo 190 T4 temperature data logger will help you to meet these requirements effectively.

Provide cover: testo 190 T4 temperature data logger, large battery, distance adapter, user manual and factory test paper.

Advantages of the testo 190 T4 temperature logger

  • High precision: testo 190 T4 data logger with long, flexible double measuring head (length 775 mm; ø 1.5 mm), memory for up to 30,000 measurement values per channel
  • Long, flexible dual probe: ideal for sterilization applications, measuring surface temperatures in refrigeration systems, determining the acclimation time between internal and external temperatures. When combined with the probe holder (optional), you can accurately measure the surface temperature of panels in refrigeration systems
  • Compact design: testo 190 T4 with 20 mm diameter, ideal for use in confined, cramped spaces
  • High-quality materials and innovative construction make the testo 190 T4 particularly robust and durable.
  • Quick and easy battery change: the battery is mounted directly on the logger, changing in seconds by hand without any additional tools
  • Reliable: the testo 190 T4 remains watertight even after battery replacement.
  • The battery case is made of high temperature resistant polyether ether ketone (PEEK)
  • The height of the logger can be flexibly changed thanks to the battery design with 2 different sizes. The small battery makes the size of the logger particularly compact. The large battery is suitable for measurements at low temperatures, for example in freezer systems.

Programming, readout and analysis of the testo 190 CFR temperature data logger

In addition to being used for storage, the versatile suitcase can also be used to program and read up to eight testo 190 loggers at the same time. This helps you save time and work more efficiently.

With testo 190 CFR software specially developed to meet 21 CFR part 11 (optional to order), you can program and read the logger, as well as analyze measurement data on the computer. Clear software interface, intuitive guidance through step-by-step process. During the data entry process, this software also sends warnings at important points. This allows users to easily manipulate and use even without much experience.
