The HiTemp140 is a rugged, high precision, temperature data logger that is built for use in harsh environments. This stainless steel device is submersible and can withstand temperatures up to 140°C (284°F). With the HiTemp140’s standard calibration, an accuracy of ± 0.1°C (± 0.18 °F) can be achieved over a wide temperature range.

The HiTemp140 can store up to 32,700 readings, and features a rigid external probe capable of measuring extended temperatures, up to 260°C (500°F). Custom probe lengths are available up to 7 in. The device records date and time stamped readings, and has non-volatile solid state memory which retains data even if the battery becomes discharged.

Using the MadgeTech Software, starting, stopping and downloading the HiTemp140 is simple and easy. To use, simply place the HiTemp140 in the IFC400 or IFC406 docking station (sold separately). Using the software, an immediate or delay start can be chosen, as well as the reading rate. Start the data logger, remove it from the docking station and the device is ready to be deployed. Graphical, tabular and summary data is provided for analysis and data can be viewed in °C, °F, K or °R. The data can also be automatically exported to Excel® for further calculations.

The HiTemp140-TSK is a kit that includes a HiTemp140 data logger with either a 5.25 in probe or a 7 in probe style, housed in a thermal shield. The combined features of the 0.1% accuracy of the HiTemp140 and the properties of the durable thermal shield allow the device to be used for a wide range of validation applications. This rugged system can be placed in and withstand temperature from -200ºC - 250ºC, making it ideal for use in autoclave validation, monitoring food processing and dishwasher testing. The HiTemp140-TSK can be completely submerged and is built for applications that require extreme temperature monitoring. The HiTemp140-TSK flush style is designed to have the probe entirely exposed while the data logger is protected by the thermal sheild. This allows full use of the length of the probe for applications that require internal temperature monitoring. The Vented style offers more probe protection and is designed for shorter probe lengths in applications where the data logger might be subject to movement in a fully submerged application.
