PCE Cryo data logger PCE-LTD 100

The PCE-LTD 100 Cryo data logger can record temperatures in the range of minus 80 to plus 70 °C. The prefix cryo comes from the Greek language, where kryos stands for cold. The cryo data loggers are therefore devices that can measure and record particularly low temperatures. With a measuring range from minus 80 °C, the PCE-LTD 100 cryo data logger is suitable, for example, for temperature recording during the transport and storage of blood plasma, vaccines and dry ice made of solid carbon dioxide.

Especially for the transport of vaccines in connection with Covid-19, the verification of fully maintained cold chains from production to vaccination is particularly important. Since some vaccines have to be transported at very low temperatures, this also requires the use of measurement technology specially suited for this purpose. Vaccines that have to be stored at - 70°C, for example, are sometimes transported in special containers with dry ice. Dry ice is solid carbon dioxide which sublimates at approx. 78.5°C. These are temperature ranges which are ideally suited for measuring vaccines. These are temperature ranges which are perfectly suitable for various vaccines.

With a Cryo Data Logger it is possible to control and prove that these temperatures have been maintained over the entire time during transport as well as during storage according to the recommendations of the WHO. A Cryo Datalogger can also be used for vaccines that only need to be stored at refrigerator temperatures. Due to the robust and compact design and the special battery adapted to the conditions, the Cryo data logger can be used without any problems in a wide variety of refrigerated containers and cooling devices.

The high degree of protection IP 67 ensures that water and foreign bodies do not penetrate the Cryo data logger and allows thorough and hygienic cleaning. The special battery is suitable for low temperatures, but has a much shorter runtime at cryogenic temperatures. At temperatures between minus 80 °C and minus 70 °C, for example, the Cryo data logger can store measurement data at 15-minute intervals for 30 days with this battery. The Cryo data logger has the highest accuracy of ±0.5 °C in the temperature range from -30 °C to +70 °C. In the range from -80 °C to -31 °C, the accuracy is ±1 °C. The Cryo data logger has an internal memory for 17,280 measurement data. Measurement start, stop mode and storage interval can be conveniently set on the PC using the supplied software. The recording of the data is stopped as soon as the Cryo data logger is connected to the USB interface of a computer, regardless of the stop mode set. In addition, the Cryo data logger stops recording when the memory space is completely occupied.

In the software, the temperature unit and alarm limits can be set and adjusted for each measurement. To read out the measurement data, the Cryo data logger must be connected to the USB interface of a computer. The computer automatically recognizes the Cryo Datalogger as a mass data storage device, so that measurement data can also be transferred as a PDF independently of the operating system and software. The software for the Cryo Datalogger provides various functions for evaluating the recorded data and offers export to other programs in a format suitable for these programs.

For documentation or further processing, the measurement data recorded by the Cryo data logger can be output, for example, in the file formats XLS, CSV, PDF, TXT or CIN. The graphical representation of the temperatures can be exported as a JPG file. The Cryo data logger can also be configured to automatically output a file with the measured data in a previously selected file format. The file formats PDF, DLG, CSV, XLS and TXT can be selected for this purpose. This option offers the particular advantage that the measurement data can be imported directly into a data management system.
