Whether you’re grilling steaks, baking pizza, or checking food safety in a commercial kitchen, accuracy matters. The IR thermapen is a powerful dual-function thermometer that combines the speed and precision of an instant-read probe with the convenience of infrared surface temperature scanning—all in one compact device.
In this post, we’ll explore what the IR thermapen is, how it works, its key features, and why it’s a must-have for both home cooks and professional chefs.
What Is the IR Thermapen?
The IR thermapen is a professional-grade thermometer made by ThermoWorks, known for its high-precision culinary tools. What sets it apart is its dual-sensor technology:
- ✅ Infrared Sensor (IR): Measures surface temperatures without contact.
- ✅ Fold-out Probe: Gives instant, internal temperature readings with pinpoint accuracy.
This makes the IR Thermapen ideal for a wide range of tasks—from checking grill surface temps to verifying the internal doneness of meats.
Key Features of the IR Thermapen
Here’s why the IR thermapen stands out from other thermometers:
| Feature | Benefit |
|---|---|
| Dual-Sensor (IR + Probe) | Measures both surface and internal temps |
| Ultra-Fast Read Time | 2–3 second readings from the probe |
| High Accuracy | ±0.7°F (±0.4°C) for internal temp, ±1.8°F for IR |
| Wide Temperature Range | Probe: -58 to 572°F / IR: -67 to 662°F |
| Adjustable Emissivity | For accurate readings on different surfaces |
| Auto-Rotating Display | Easy to read from any angle |
| Backlit Screen | Great for low-light cooking or outdoor grilling |
| Durable Design | Water-resistant and shockproof |
How to Use IR Thermapen
Using the IR thermapen is incredibly simple, but understanding its two modes will help you get the most out of it.
1. Using the Infrared Sensor (IR Mode):
- Point the front-facing IR sensor at the surface (e.g., a griddle or pan).
- Press the IR button to take a surface temp reading instantly.
- Adjust emissivity settings for materials like cast iron, stainless steel, or ceramics to get accurate readings.
2. Using the Probe:
- Unfold the probe to activate the internal temperature sensor.
- Insert the probe into the thickest part of the food item.
- Wait 2–3 seconds for an accurate digital readout.
When to Use an IR Thermapen
The IR Thermapen is incredibly versatile. Here are common use cases:
| Use Case | Benefit |
|---|---|
| Grilling & BBQ | Check grill grate temperature and meat doneness |
| Pizza Ovens | Measure stone or deck surface temperature |
| Cast Iron Cooking | Know when your skillet is preheated perfectly |
| Food Safety Checks | Ensure safe holding temps in commercial kitchens |
| Baking | Monitor oven or dough surface temp |
| Sous Vide Finishing | Surface temperature of meats before/after searing |

Frequently Asked Questions (FAQs)
❓ Is the IR Thermapen waterproof?
It is splash-resistant, not fully waterproof. Avoid submerging it in water.
❓ What is emissivity and why does it matter?
Emissivity refers to how a material emits thermal radiation. Adjusting this setting on the IR Thermapens ensure accurate surface readings on different materials like stainless steel or ceramic.
❓ Can I use it for non-food applications?
Yes! IR Thermapens are useful for HVAC work, engine diagnostics, or checking appliance temperatures—just be sure to clean it properly before and after food use.
Final Thoughts
IR Thermapens are more than just a thermometer—it’s a professional kitchen essential. Its combination of infrared surface scanning and instant internal temperature measurement gives you unmatched control and confidence, whether you’re searing steaks, smoking brisket, or checking holding temperatures in a commercial setting.
If you’re serious about precision and consistency in the kitchen, IR Thermapens are investment that pays off every single time you cook.
