Ultra Extreme Thermochron Temperature Logger – TCU – 15°C to 140°C

Ideal for monitoring temperature above 60°C. This includes incubators, heating, washing and some sterilization processes.



Simple, Automated Temperature Monitoring.

Thermochron Temperature Loggers are the perfect device for continually monitoring the temperature, especially when space is limited. These tiny devices automatically record the date, time and temperature at a set interval. You can then download the results to a PC where they can be viewed, analysed and saved for later.

There’s a reason this is our most popular product – the number of applications for this Temperature Loggers is virtually endless. Thermochrons are commonly used for food fridges and freezers, vaccine fridges, transportation (solve problems with spoilage of goods), medical storage, blood storage, air conditioning and heating.

No matter what size business you are a part of, this Temperature Logger provides a low cost, easy to use solution for ensuring temperature compliance. If a problem exists, it will help identify when, for how long and how bad the problem is.


Thermochrons are made from stainless steel and so can withstand harsh environments.

Large Range

Thermochrons are one of the only temperature loggers that can be used at 140°C without an external probe.

Powerful Software

Use this Thermochron with eTemperature control and reporting software, designed and developed by us here in Australia.


Details on the TCU Logger


The TCU temperature logger is a rugged, self-sufficient system that measures temperature and records the result in a protected memory section. The recording is done at a user-defined rate. A total of 8192 8-bit readings or 4096 16-bit readings, taken at equidistant intervals ranging from 1s to 273hr, can be stored. Additionally, 576 bytes of SRAM store application-specific information. A mission to collect data can be programmed to begin immediately, after a user-defined delay, or after a temperature alarm. Access to the memory and control functions can be password protected. The TCU is configured and communicates with a host-computing device through the serial 1-Wire® protocol, which requires only a single data lead and a ground return. Every TCU is factory lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability. The durable stainless-steel package is highly resistant to environmental hazards such as dirt, moisture, and shock.

While all data loggers are calibrated/validated against NIST traceable reference devices, OnSolution offers a web application to generate validation certificates for the DS1922L/T data loggers. Input is an registration number (or list of numbers) and the output is a validation certificate in PDF format.
