Thermapen® ONE Blue

Streamline restaurant line checks and protect your brand with TempTest Plus Blue, an advanced handheld thermometer engineered for commercial food safety and processing operations. Eliminate tedious paper logs and empower staff to make immediate decisions using real-time information directly on screen. Featuring a high-contrast, auto-rotating dot-matrix display, operators can instantly view active checklist items, allowable temperatures, live readings, and pass/fail status right on the device.

Built for demanding workstations, a recessed top-mounted port accepts all standard Type K thermocouple probes, plug-mount or cabled. Bluetooth connects seamlessly to the ThermoWorks App and Cloud, or your own software provider to digitize HACCP audit trails for total compliance. Backed by rugged IP67 waterproof housing, 1,000-hour AAA battery life, NSF certification, and a NIST-traceable calibration certificate (±0.7°F accuracy), it delivers complete inspection readiness. 

Two professional instruments in one! Now with Bluetooth® Wireless Technology!

Go paperless with Thermapen IR Blue! Get your temp checks done more accurately, faster, and without paper recording errors. Use the ThermoWorks mobile app and Cloud for quick access to your data, or integrate with your existing software platform through your integration partner.

Thermapen IR Blue combines the unparalleled speed and accuracy of a Classic Thermapen with the versatility of an instrument-grade infrared sensor with Bluetooth technology. Why carry two different thermometers when you can just carry the Thermapen IR?

View both infrared and penetration probe readings from either hand in any position with Thermapen IR's patented 360° auto-rotating display. Close the probe when you're done and it powers off for storage. Each unit ships with a NIST-traceable calibration certificate for both the probe and infrared so you know it's accurate.

Thermapen IR is a must-have, versatile tool for restaurants, health inspectors, manufacturing, laboratory, and more.

Infrared thermometer
Take non-contact infrared readings from virtually any surface with Thermapen IR Blue's precision infrared circuitry. Simply aim the infrared end of the thermometer at the target and press the Scan button to display the surface temperature, accurate to within ±1.8°F (±1.0°C).

The Thermapen IR Blue thermometer incorporates a Max/Min reading feature accessed through the Mode button (IR only). The distance-to-target ratio is 5:1, so the thermometer should be positioned as close to the target as possible. The default emissivity is 0.95, but can be adjusted between 0.1 and 1.0 as needed through the Mode button.

Please Note: Because the unit needs an opening to allow infrared wavelengths to fall upon the infrared sensor inside the housing, the Thermapen IR Blue does not have the same Splash-Proof rating that other Thermapen's have and should be kept away from splashes and spills.

Penetration probe
Incorporating the Thermapen Super-Fast® thermocouple technology, penetration measurements come to a reading accurate to ±0.7°F (±0.4°C) within just 2-3 seconds. The probe conveniently folds back into the side of the instrument for safe storage when not in use.

Thermapen IR Blue comes with a NIST-traceable calibration certificate confirming the accuracy of both sensors.
