The HiTemp140 is a premier high-temperature data logger uniquely engineered for performance in harsh environmental conditions. This submersible unit is crafted to deliver reliable data logging in industries where temperature accuracy is critical. With its robust stainless steel design, the HiTemp140 is especially suited for applications in pharmaceuticals, food processing, and industrial manufacturing. These sectors demand precise monitoring tools that can withstand not only high temperatures but also the rigorous cleaning processes often required in such settings.
The HiTemp140 operates within a standard temperature range of -40 °C to +140 °C (-40 °F to +284 °F), making it a robust tool for a variety of high-temperature applications. For processes that reach higher temperatures, the HiTemp140-5.25, HiTemp140-7, HiTemp140-FP and HiTemp140-PT can be used with thermal barriers including the HiTemp140-TS, which can extend the temperature range up to 250 °C (482 °F).
The HiTemp140 is available with a variety of probe lengths and styles, each designed for specific scenarios and applications. The selection of a probe depends on factors such as the nature of the medium being monitored, the required insertion depth, and the environment’s physical space constraints. With a substantial storage capacity for up to 32,256 time and date-stamped readings, the HiTemp140 can continuously record data over extended periods.
Additionally, it is fully compatible with the MadgeTech 4 Data Logger Software, which facilitates straightforward setup, comprehensive data management, and detailed analysis. This software compatibility enhances operational efficiency and ensures precision in data logging tasks, making it an ideal choice for rigorous monitoring needs.

Body of data logger cannot exceed 140 °C (284 °F), but can extend to higher temperatures when used with MadgeTech’s thermal barrier options.
