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.
Device Maintenance
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
.
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).
