The MadgeTech HiTemp140 Autoclave Temperature Data logger 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, from 20°C to +140°C (68°F to +284°F).

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 inches. Each data point is date/time stamped and saved in non-volatile solid state memory, even if the battery becomes discharged.

Using the MadgeTech Software, starting, stopping and downloading the HiTemp140 is simple and easy. 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.

Applications for the MadgeTech HiTemp140

  • Autoclave verification
  • Implement HACCP programs
  • Food preparation and processing
  • Environmental studies
  • Well monitoring
  • Dishwasher testing
  • Pasteurization

Application Notes

Here's how some of our customers used this product.

Autoclave Validation

The Background: Our customer is a research company that wants to verify the temperature displays of their autoclaves to make sure the readouts are correct and not in need of calibration.

The Problem: The temperatures and pressures associated with autoclaves are beyond that capabilities of most data loggers.

The Solution: We suggested the MadgeTech HiTemp140 autoclave temperature data logger which is specifically designed for use in autoclaves. It is a rugged, high precision, data logger that is right at home in harsh environments. This stainless steel device is submersible and can withstand temperatures up to 140°C (284°F). Multiple units could be used on large systems for temperature mapping.
