The probe supplied with the TM1A is a highly accurate temperature sensor. The sensor may be put in
water or other mild aqueous solutions.
NOTE: Avoid submerging the probe in solvents or harsh chemicals. Use protective thermowells
when monitoring such materials.
NOTE: The warranty does NOT cover damage to probes or electronics that is caused by exceeding
temperature limitations, or damage to probes caused by using them in solvents or
other unsuitable environments.
NOTE: If the display shows a continuous reading of 199.9, the probe has failed. Replace the probe
and recalibrate the unit.
Probe Installation
The probe may be used in air or in a simulated product, such as glycol.
If installing the sensor in a cabinet or enclosure (particularly freezers), make sure to use good
techniques to prevent room moisture from getting into the cabinet. Whenever possible, install the
probe through an existing access port provided by the cabinet manufacturer, then reseal the port.
Alternatively, the probe can be run under, over, or through the door-sealing gasket. Often a door
gasket will have a joint at one or more corners. Open that joint slightly by carefully making a slit with a
razor blade. Insert the probe wire and then reseal the joint with a flexible silicone sealing compound.
Inside the cabinet, run the probe wire so that it will not become snagged during loading, unloading, or
cleaning procedures.
