ThermoWorks Classic Thermapen Operating Instructions

Classic Thermapen
Congratulations
Classic Thermapen is a precision thermometer used for many applications including cooking.
With proper care it will offer accurate measurements for many years. Classic Thermapen is
splash-proof but should not be immersed.
Rotating hub
The micro-thermocouple sensor is located at the tip of the probe shaft. Minimum immersion
is only 1/8" (3 mm). For best results immerse or penetrate the probe into the food item so the
probe tip is in the place you want to measure. In food, this should normally be the thickest
part.

Operating Instructions

Instrument Operation

The instrument is switched on by unfolding the thermo-
couple probe until the display comes on. Conversely, the
instrument is turned off by folding the probe away and lightly
pressing the tip into the rubber probe retainer located at the
bottom rear of the instrument. It is recommended to store
the probe when not in use.
Do not force the probe further than 180° or damage to
the rotating hub may occur.
Classic Thermapen will read to within 1°F of the final tem-
perature of an ice bath within three seconds. Reading times in
other foods may vary slightly.
Do not immerse the probe all the way to the plastic
rotating hub. Avoid getting flour, moisture, or oil on
the hub itself. Although there is an O-ring seal, oils
will work their way past the seal and accumulate in-
side the hub and may cause failure. The probe tip is
sharp. Use caution to avoid injury. Do not "stab" the
material to be measured. Use steady force to pen-
etrate meats or semi-solids. Avoid bone. Do not lift or
flip heavy meats with the probe tip. The probe shaft
is hollow and contains a sensor. If bent, it may fail.
