Product Overview
The ThermoVault Max is an extreme, high temperature
thermal barrier designed for use with the HiTemp140
series. This durable thermal barrier can withstand

+250 °C in wet applications when used with the TMAX Wet
Seal Kit (optional accessory).
Compatible Data Loggers
• HiTemp140-M12
• HiTemp140-FP
• HiTemp140-PT
Getting Started
Dry Applications
The HiTemp140-FP, HiTemp140-PT HiTemp140-M12 can
be used for dry applications up to +400 °C.
1. Unscrew the lid of the
thermal barrier.
3. If using the HiTemp140-M12
data logger, screw the
probe into the bottom end
of the barrier lid.
4. Slide the data logger and
lid back into the barrier

Wet Applications
For use in wet applications, the TMAX Wet Seal Kit (sold separately, optional accessory) should be used with the
HiTemp140-FP, and HiTemp140-PT data logger. When used in wet applications the maximum operating environment
cannot exceed 250 °C (482 °F).
Installing the O-Ring: The O-Ring ensures a tight seal which prevents liquid from entering the inside of the barrier. O-Ring
maintenance is a key factor when properly caring for the ThermoVault Max. Please refer to the application note “O-Rings
101: Protecting Your Data Logger,” found on the MadgeTech website, for information on how to prevent O-Ring failure.
The TMAX Wet Seal Kit Includes:
• PTFE Thread Sealing Tape
• Fitting Body
• Dome Nut
• Compression Ferrules: PTFE (5), Stainless Steel (1)
• O-Ring
1. Unscrew the endcap of the
thermal barrier.
2. Stretch the O-Ring over the
endcap so it sits in the groove just
beneath the knurled shoulder.

Securing the Compression Fitting: The compression fitting is used with the HiTemp140-FP and HiTemp140-PT data
loggers to ensure a water tight seal.
Compression Ferrule Note: The
stainless steel Ferrule provides the
most reliable seal, but becomes
permanent crimped onto the probe.
The PTFE Ferrule will become more
deformed with multiple uses and will
eventually require replacement. It’s
benefit is that it allows easy removal
and repositioning of the probe.
1. Wrap the provided PTFE thread
sealing tape around the Fitting
Body threads.
2. Screw the Fitting Body into the
end of the stopper assembly
(finger-tight).
3. Holding the smooth metal end of
the stopper, use a 7/16” wrench
or socket to tighten the body into
the stopper.
4. Insert the Compression Ferrule
into the Fitting Body and hold it in
place loosely with the Dome Nut.
5. Feed the data logger probe throw
the Compression Fitting until
the base of the probe is tightly
against the Dome Nut.
6. Tighten the Dome Nut to secure
the data logger in place (finger-
tight).
7. Insert the data logger and stopper
assembly back into the thermal
barrier and screw the endcap
of the thermal barrier until the
O-Ring is no longer visible.
