HiTemp140
Product Notes
The HiTemp140 is a rugged, high precision, temperature data logger that is built for use with
autoclaves and harsh environments. This stainless steel device is submersible, can withstand
temperatures up to 140 °C (284 °F) and has an accuracy of +/-0.1 °C (0.18 °F).
Product User Guide
- 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 docking station and place it in the environment to
measure.
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 up to
7 inches are available. The device records date and time stamped readings, and has non-
volatile solid state memory that will retain data even if the battery becomes discharged. The
HiTemp140 can be used in both wet and dry applications up to 140 °C indefinitely.
Submergibility
The HiTemp140 is fully submersible and is rated IP68. It can be placed in environments with
up to 230 feet (70 m) of water.
O-Rings
O-ring maintenance is a key factor when properly caring for the HiTemp140. 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 on the MadgeTech website,
for information on how to prevent O-ring failure.
Note: This product is rated for use up to 140 °C. Please heed the battery warning. The product will explode if exposed to
temperatures above 140 °C.
Installation Guide
Installing the Interface cable
- IFC400 or IFC406
Refer to the “Quick Start Guide” included in the package.
Installing the software
The Software can be downloaded from the MadgeTech website at madgetech.com. Follow
the instructions provided in the Installation Wizard to install the MadgeTech Software.
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.)
Note: The device will stop recording data when the end of memory is reached or the device is stopped, unless user selectable
memory wrap is enabled. 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.
Device Maintenance
Battery Replacement Warning
When replacing 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.
Recalibration
Recalibration is recommended annually. To send devices back for calibration, visit
madgetech.com.
