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

Disclaimer & Terms of Use
Listed specifications can be used to determine maximum allowable
exposure times for the HiTemp140 with ThermoVault Max. The barrier
extends the operating temperature of the logger up to, but not
exceeding, the measurement range. Please consult the measurement
range of the probe for temperatures above 250 °C (482 °F).
Both the data logger and ThermoVault Max must be at ambient
temperature, approximately 25 °C (77 °F) before being placed in the
extreme temperature environment. Immediately following exposure
to high temperature, the data logger should be removed from the
ThermoVault Max, using appropriate precautions, as it could be VERY
hot. Failing to remove the data logger may allow heat trapped in the
ThermoVault Max to continue to heat the data logger to potentially
unsafe levels.
The ThermoVault Max may take hours to fully cool down. Even if the
exterior of the ThermoVault Max is cool to the touch, the interior of the
barrier and its contents may still be VERY hot.
The ThermoVault Max is primarily intended for use in dry air
environments, but with the addition of the TMAX Wet Seal Kit, the
ThermoVault Max may also be used in liquids and steam environments.
If your application involves a ramp up to a temperature above 150 °C
(302 °F) and/or any complex temperature profile that isn’t a constant
process, please contact MadgeTech to determine whether the
HiTemp140 with ThermoVault Max is suitable for the application.
To determine if the HiTemp140 with ThermoVault Max is suitable for
the application, please provide MadgeTech with a detailed description
of your process, including temperatures, durations, ramp times and
process media such as air, steam, oil or water. If MadgeTech is unable to
definitively calculate the suitability of our product for your application, a
test unit outfitted with a high temperature indicator can be provided.

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.)
6. The status of the device will change to Running,
Waiting to Start or Waiting to Manual Start,
depending upon your start method.
7. 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
1. Place the logger into the docking station.
2. Highlight the data logger in the Connected Devices
list. Click Stop on the menu bar.
3. Once the data logger is stopped, with the logger
highlighted, click Download. You will be prompted to
name your report.
4. Downloading will offload and save all the recorded
data to the PC.

Device Maintenance
O-Rings
O-ring maintenance is a key factor when properly caring
for the HiTemp140-M12. 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
1. Unscrew the bottom of the logger
and remove the battery.
2. 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.
3. Screw the cover back onto the logger.
Recalibration
MadgeTech recommends annual recalibration. To send
devices back for calibration, visit madgetech.com.
