Thermapen ONE
Congratulations
Thermapen ONE is a precision thermometer used for many applications, including
cooking.
With proper care, it will offer accurate measurements for many years.
Thermapen ONE includes several new features, including: one-second response
time and increased accuracy.
Instrument Operation
The instrument is switched on by unfolding the thermocouple 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 in
the closed position when not in use.
Do not force the probe further than 180° when opening or damage to the
rotating hub may occur.
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 at the center of the thickest part.
Thermapen ONE will read to within 1°F of the actual temperature of an ice bath
within one second. 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 can work
their way past the seal and accumulate inside 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 penetrate 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.
Instrument Configuration
You can personalize your Thermapen ONE by changing several factory default
settings including:
Temperature display from °F to °C
Display resolution from 1° to 1.0°
Screen Rotation
Auto-Off/Sleep Mode
To change any of these settings, loosen the battery cover screw using a Phillips screwdriver and remove the battery cover. Open the probe to turn the unit on. Thermapen ONE has two small buttons inside the battery compartment: MENU, which is used to enter, save settings, and exit the menu; and SET, which is used to select desired settings.Settings are saved once ‘END’ is displayed at the end of the menu options. To abort settings, close the probe. Press the MENU button to cycle through the following settings:
Temperature Display Units, °F to °C
Press the MENU button until ‘C or F’ is displayed. Press SET to toggle between
‘°F’ and ‘°C’ as displayed in the upper right hand corner of the display. When
the selection is complete, press MENU to store setting.
Display Resolution, 1° to 1.0°
Press the MENU button until the current resolution setting ‘0.1°’ or ‘1°’ is
displayed. Press SET to toggle between ‘0.1°’ and ‘1°’. When the selection is
complete, press MENU to store setting.
Screen Rotation
Press the MENU button until ‘DISPLAY’ is shown at the top of the display.
Press SET to select ‘360°’ for full 4-way rotation, ‘180°’ for 2-way rotation
(horizontal only), or choose to lock the display in a specific orientation
when ‘Loc’ is displayed. Press MENU to store the rotation setting.
Auto-Off/Sleep Mode
Press the MENU button until ‘SLEEP’ is shown at the top of the display. Press
the SET button to step through the sleep interval settings from ‘10’ seconds
to ‘180’ seconds in 10-second intervals, or to turn the sleep function ‘off.’
Press MENU to store the sleep interval and the instrument will enter sleep
mode at the specified number of seconds without movement detected. END will
flash momentarily to show that all settings are saved.
Note: When the probe is open and the instrument is in sleep mode, any
motion detected by the Thermapen will conveniently wake the instrument and
turn it back on.
When you are done adjusting settings, replace the battery cover and tighten
the battery cover screw with a Philips screwdriver. Do not overtighten.
Intelligent Backlight
When the Thermapen ONE is turned on, a light sensor (small round window located just to the right of the main display) continuously monitors ambient light levels. As it gets darker, the intelligent backlight comes on automatically to read the digits in any light condition. Covering the light sensor will also turn on the backlight except in well-lit areas. The backlight will remain on for a minimum of 10 seconds. If the instrument is displaying the low battery symbol, the backlight brightness will be reduced to prolong battery life.
Batteries
Each instrument includes one pre-installed AAA (1.5V) battery located inside
the sealed battery compartment. An illuminated battery symbol ( ) in the LCD
display indicates
that the battery should be replaced soon. The instrument will continue to
measure accurately, but it is recommended to replace the batteries immediately
(in low battery condition, the backlight brightness will be reduced to prolong
battery life). Once the battery is too low to display readings, the display
will be replaced with ‘Flat’ then ‘Bat’ and then shut down.
To continue using the instrument, replace the battery.
Replacing the Battery
The battery is pre-installed on your new Thermapen ONE and should last up to
2,000 hours. Should you need to replace the battery, loosen the battery cover
screw using a Phillips screwdriver to remove the battery cover. Replace with a
single AAA battery noting the polarity. Tighten the battery cover screw until
the battery cover is snug onto the seal. Do not overtighten.
Cleaning and Maintenance
To avoid potential bacteria growth and cross-contamination, wipe the probe after each use and regularly clean the entire Thermapen ONE body. Oils and grease should be wiped off the body and the rotating hub. We recommend sanitizing wipes or a damp paper towel with an anti-microbial cleaning solution. Protected from dust and immersion in water to 39” depth for up to 30 minutes. The probe should not be rotated while the body is submerged or under a stream of water. Protect the plastic body from high temperatures. DO NOT LEAVE THE THERMAPEN ONE IN AN OVEN OR ON A HOT SURFACE. Not dishwasher safe.
Warning
IPA and other solvents may cause damage to the case and screen of this
instrument.
Error Messages
- ‘Lo’ is displayed if measurements are being made below the instrument range.
- ‘Hi’ is displayed if measurements are being made above the instrument range.
- ‘Err’ is displayed if the probe develops a fault. Call for details.

What is NSF Certification?
The NSF mark indicates that the design, materials, production process, and
quality controls used in the production of Thermapen ONE have been verified
and certified for food safety by NSF International, an independent standards
organization.
Biomaster
Biomaster is a silver-based antimicrobial additive that is molded directly
into the plastic housing that becomes an integral part of the product to
prevent bacteria growth on its surface.
The controlled release of the active ingredient provides maximum antimicrobial
protection for the life of the product. When bacteria come into contact with a
Biomaster protected surface, the silver ions prevent them from growing,
producing energy or replicating, therefore they die, inhibiting degradation,
discoloration or odors. Biomaster is an additional line of defense between
cleanings.*
NIST-traceable Calibration Certificate
Your calibration certificate is a document showing that your very own
Thermapen ONE is in compliance with key industrial regulations and that its
performance meets certain key standards for high performance. This means that
your Thermapen ONE was tested in our calibration lab and those measurements
taken are traceable by an unbroken, documented chain of calibrations to the
National Institute of Standards and Technology (NIST).
