Availability: 5-7 Business Days


* Required Fields

The HiTemp140-FP is a durable, user friendly high temperature data logger featuring a long, flexible RTD probe with a narrow diameter, making it ideal for use in steam sterilization and lyophilization processes.

Commonly used for mapping, validation and monitoring of high temperature surfaces and environments, this stainless steel data logger is available in several flexible probe lengths. The flexible probe is coated with PFA insulation and can withstand temperatures up to 260 °C (500 °F) with an accuracy of ±0.1 °C.

The HiTemp140-FP probe design is narrow and lightweight making it ideal for placement within small vials, tubing, test tube and other small diameter or delicate applications. Because of the flexible probe, the risks of breakage (both vial and probe) generally associated with stainless steel probe loggers are diminished and the location and placement of the probe is easy to manipulate. The device records and stores up to 32,700 time stamped readings and is equipped with non-volatile solid state memory.

The HiTemp140-FP can be configured for delayed start and is capable of reading rates as often as four readings per second, up to once every 24 hours.

Compatible with the latest MadgeTech Data Logger Software, starting, stopping, and downloading data is simple and reporting capabilities are abundant. The device connects to a PC with the IFC400 interface or the IFC406 docking station (sold separately). Downloaded data can be viewed in graphical, tabular, and summary data form in the MadgeTech software, and all data can be exported to Excel® for further analysis and calculations.

Notice: Steam Sterilization Applications

The pervasive nature of pressurized steam creates a very difficult environment for electronics.
Please refer to the following preventative maintenance procedure when using this device in steam sterilization applications.

Additionally, this device is not ideal for steam sterilization applications above 121 °C/1.1 bar.

  1. great tool Review by keith

    we use this in our rotating rack ovens to capture all the data required for our SQF facility .device is easy to use, software is very intuitive. absolutely no complaints Ok maybe a little expensive but worth every penny.
    taking a piece of electronics that you paid $500++ for putting it in the oven and cooking it until its so hot you cant touch it is a little un nerving but we have used it 100 times easy and no issues at all.
