MADGETECH HiTemp140-FP High Temperature Data Logger with Flexible RTD Probe User Guide
Product Overview
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, this stainless steel data logger is available in several models. The flexible probe is coated with PFA insulation and can withstand temperatures up to 260 °C (500 °F ) with an accuracy of ±0.1.
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 Trigger Settings feature of the HiTemp140-FP allows users to configure high and low temperature thresholds that when met or exceeded, will automatically start or stop recording data to memory. This data logger is capable of storing up to 65,536 date and time stamped readings and features a non-volatile solid state memory which retains data even if the battery becomes discharged.
Water Resistance
The HiTemp140-FP is rated IP68 and is fully submersible.
Installation Guide
Installing the Software
The Software can be downloaded from the MadgeTech website at
madgetech.com. Follow the instructions provided in the
Installation Wizard.
Installing the Docking Station
IFC400 or IFC406 (sold separately) — Connect the device into a USB port with
the interface cable. The drivers will install automatically.
Device Operation
Connecting and Starting the Data Logger
-
Once the software is installed and running, plug the interface cable into the docking station.
-
Connect the USB end of the interface cable into an open USB port on the computer.
-
Place the data logger into the docking station.
-
The data logger will automatically appear under
Connected Devices within the software. -
For most applications, select Custom Start from the menu bar and choose the desired start method, reading rate and other parameters appropriate for the data logging application and click Start. (Quick Start applies the most recent custom start options, Batch Start is used for managing multiple loggers at once, Real Time Start stores the dataset as it records while
connected to the logger.) -
The status of the device will change to Running, Waiting to Start or Waiting to Manual Start, depending upon your start method.
-
Disconnect the data logger from the interface cable and place it in the environment to measure.
Note: The device will stop recording data when the end of memory is reached or the device is stopped. At this point the device cannot be restarted until it has been re-armed by the computer.
Downloading Data from a Data Logger
- Place the logger into the docking station.
- Highlight the data logger in the Connected Devices list. Click Stop on the menu bar.
- Once the data logger is stopped, with the logger highlighted, click Download. You will be prompted to name your report.
- Downloading will offload and save all the recorded data to the PC.
Trigger Settings
The device can be programmed to only record based off user configured trigger
settings.
- In the Connected devices panel, select the intended device to change the settings.
- On the Device tab, in the Information group, click Properties. Users can also right-click on the device and select Properties in the context menu.
- Click Trigger and configure the Trigger settings.
Trigger formats are available in Window and Two Point (bi-level) mode. Window mode allows for one range of temperature monitoring and two point mode allows for two ranges.
Note: This product is rated for use up to 140 °C (284 ºF). Please heed the battery warning. The product will explode if exposed to temperatures above 140 °C (284 ºF).
Set Password
To password protect the device so that others cannot start, stop or reset the
device:
- In the Connected Devices panel, click the device desired.
- On the Device Tab, in the Information Group, click Properties. Or, right-click the device and select Properties in the context menu.
- On the General Tab, click Set Password.
- Enter and confirm the password in the box that appears, then select OK.
Device Maintenance
O-Rings
O-ring maintenance is a key factor when properly caring for the HiTemp140-FP.
The O-rings ensure a tight seal and prevent liquid from entering the inside of
the device. Please refer to the application note O-Rings 101: Protecting Your
Data, found at madgetech.com, for information on how
to prevent O-ring failure.
Battery Replacement
Materials: ER14250MR-145 Battery
-
Unscrew the bottom of the logger and remove the battery.
-
Place the new battery into the logger. Note the polarity of the battery. It is important to insert the battery with positive
polarity pointing upward towards the probe. Failure to do so could result in product inoperability or potential explosion if exposed to high temperatures. -
Screw the cover back onto the logger.
Recalibration
MadgeTech recommends annual recalibration. To send devices back for
calibration, visit madgetech.com.
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.
Preventive Maintenance
After every 3 hours of steam exposure:
- Remove the endcap and battery from the device (ref. battery change procedure on Product User Guide)
- Place open logger (minus battery) in an oven at 120 °C (250 °F) for a minimum of 30 minutes
- Remove logger from oven and allow to cool to room temperature
- Re-assemble the logger with the battery (note polarity) and endcap
Note: This product is rated for use up to 140 °C (284 ºF). Please heed the battery warning. The product will explode if exposed to temperatures above 140 °C (284 ºF).

Disclaimer & Terms of Use
Published specifications can be used to determine maximum allowable exposure
times for the HiTemp140 with Thermal Shield at different temperatures beyond
the normal operating range of the logger. Both the data logger and Thermal
Shield must be at ambient temperature (approximately 25 °C) before being
placed in the extreme temperature environment.
Immediately following exposure to high temperature, the data logger should be removed from the thermal shield (using appropriate precautions, as it could be VERY hot) OR the data logger and shield should be placed in a water bath (approximately 25 °C) for at least 15 minutes to allow it to cool. Failing to do this may allow heat trapped in the Thermal Shield to continue to heat the data logger to potentially unsafe levels.
If your application involves a ramp up to a temperature above 140 °C and/or any complex temperature profile that isn’t simply a constant temperature, please contact MadgeTech to determine whether the HiTemp140 with Thermal Shield is suitable.
Please provide MadgeTech with a detailed description of your temperature profile, including temperatures, durations, ramp times, and process media (air, steam, oil, water, etc.) If MadgeTech is unable to definitively calculate the suitability of our product for your application, we can provide a test unit outfitted with a high temperature indicator sticker. This sticker has an indicator dot which will turn black if exposed to temperatures above 143 °C. Apply the sticker to the bottom of the data logger itself (not the thermal shield), remove the battery for safety, place the data logger into the thermal shield and run the assembly through the proposed temperature program. The first indicator dot on the sticker will turn black at 143 °C. If that happens, the HiTemp140 with thermal shield is not appropriate for the application and we will work to find a solution that is.
