MadgeTech has designed a series of data loggers specifically for validating temperature and pressure within autoclaves. These rugged, stand-alone, fully-submersible devices can be placed directly inside the autoclave with the product(s), providing an overall temperature and pressure profile to validate the entire sterilization cycle.

High Temperature Data Loggers

The HiTemp140 series data loggers are MadgeTech’s solution for precise high temperature monitoring. These data loggers can indefinitely withstand temperatures of up to 140 °C (284 °F). The HiTemp140 features a rigid external RTD probe capable of measuring extended temperatures, up to 260 °C (500 °F). Varied probe lengths are available up to 7 inch. The HiTemp140-PT features a 24 inch flexible steel RTD probe capable of measuring extended temperatures, up to 350 °C (662 °F).

The HiTemp140X2 series of dual probe high temperature data loggers offer extreme flexibility for high temperature monitoring applications. This product is ideal for applications such as autoclave validation, sterilization processes and much more.

The HiTemp140-FR is a high temperature data logger with an ultra-fast response time, to record temperature during rapidly changing thermal processes. This high temperature data logger is capable of recording as fast as 4 Hz. The HiTemp140-FP probe design is narrow and lightweight making it ideal for placement within small vials, test tubes and other small diameter or delicate applications. The flexible lightweight probe with stainless steel tip minimizes the risks of breakage (both vial and probe) and makes placement of the probe easy to manipulate.

The HiTemp140-M12 is a high temperature data logger designed with a built in M12 probe connecter. This logger is compatible with dozens of M12 RTD probes and capable of measuring up to 850 °C (probe dependent).


Pressure Data Logger for High Temperatures

The PR140 is a pressure data logger that can withstand pressures up to 5 Bar and temperatures up to +140 °C (+284 °F). This rugged device is completely submersible. The PR140 is built with a precision pressure sensor, offering a calibrated accuracy of ±0.03 Bar.


Autoclave Validation Data Logging System

MadgeTech offers the AVS Autoclave Validation System, which provides all of the tools needed to validate, map and monitor autoclaves and washer disinfectors. The AVS comes with all components securely packaged in a sleek and protective aluminum briefcase, ideal for storage or transporting the system to multiple facilities or locations.

PST validation kits comes with 2 different selectable packages, 2 x Temperature + 1 x Pressure Loggers OR 3 x Temperature + 1 x Pressure Loggers, along with the MadgeTech Standard software, IFC400 OR IFC406 in a shock proof carry bag.



For applications that require extended exposure to high heat, MadgeTech has developed a line of thermal enclosures for use with the HiTemp140 series data loggers. These thermal shields and barriers expand the capabilities of the HiTemp140 series, making an ideal solution for monitoring the extreme temperatures and exposure time required for effective Dry Heat Sterilization.

Dry Heat Sterilization Data Logging System

The DHS Data Logging System for Dry Heat Sterilization is an all in one solution that comes equipped with:
• HiTemp140-M12, High Temperature Data Logger
• 36 inch Glass Braided RTD Dry Heat Sterilization probe with M12 connector and flat probe tip
• ThermoVault Max, Extreme Temperature Thermal Barrier

This system is capable of withstanding and measuring temperatures up to 400 °C for 60 minutes, allowing it to record throughout the entire dry heat sterilization process. The HiTemp140-M12 data logger features the popular rugged steel body design of the HiTemp140 data logger series with the flexibility to utilize dozens of RTD probe options with M12 connection compatibility.


High Temperature Data Logger with an M12 Probe Connector

The HiTemp140-M12 features the same rugged stainless steel body as the other HiTemp140 data loggers in the series, but offers interchangeable probe options using an M12 type connector. The M12 connectivity makes this versatile data logger compatible with the large variety of M12 RTD probes available today. The HiTemp140-M12 is capable of measuring and recording temperatures from -200 °C to +850 °C (-328 °F to +1562 °F) (probe dependent).


Extended High Temperature Monitoring

For applications above 140 °C, a thermal shield is available for most models of the HiTemp140 and HiTemp140-PT series data loggers. The thermal shield extends the operating temperature of the data logger, allowing it to be exposed to higher temperatures for a longer amount of
time. Flush and vented models are available to help provide probe protection.



In accordance with ANSI/AAMI/ISO 11135, it is required for temperature and humidity levels be monitored during an EtO/EO sterilization process. MadgeTech data loggers can be used to validate these parameters to ensure an environment in which sufficient sterility levels are achieved.
