How to Use an Infrared Thermometer
Proper technique for measuring surface temperature with an infrared thermometer
Using an infrared thermometer correctly ensures you get the most accurate readings possible. Follow these simple steps:
- Hold the thermometer by its handle and point it at the target surface.
- Position yourself at the optimal distance based on your thermometer’s distance-to-spot (D:S) ratio. For a 12:1 ratio, stand 12 inches away to measure a 1-inch spot.
- Press and hold the trigger. A laser dot or pattern will appear, showing where you’re measuring.
- Keep the thermometer perpendicular to the surface for the most accurate reading.
- The temperature will appear on the digital display almost instantly.
- Release the trigger. Most models will hold the last reading for a few seconds.
Tips for Accurate Readings
Do’s
- Ensure the surface is clean and free from steam, dust, or smoke.
- Adjust the emissivity setting if your thermometer allows it (typically 0.95 for most non-metallic surfaces).
- Take multiple readings for critical measurements.
- Consider the size of the area being measured relative to your distance.
Don’ts
- Don’t measure through glass, liquids, or transparent surfaces.
- Don’t use on highly reflective surfaces without adjusting emissivity.
- Don’t expect accurate internal temperature readings (use a probe thermometer instead).
- Don’t hold the thermometer at an angle to the surface.
Remember: Infrared thermometers measure surface temperature only. For internal food temperatures (like meat doneness), you’ll need a probe thermometer.
Key Things to Know Before Buying an Infrared Thermometer
Understanding the technical specifications and features will help you select the best infrared thermometer for your specific needs. Here are the critical factors to consider:
Temperature Range
Different models offer varying temperature ranges. For cooking and household use, a range of -50°F to 750°F is typically sufficient. Professional applications like checking HVAC systems or automotive diagnostics may require ranges up to 1000°F or higher.
Accuracy
Accuracy is usually expressed as a percentage or fixed value (e.g., ±2% or ±2°F). Higher-end models offer better accuracy, which is crucial for precise applications. Most quality infrared thermometers have an accuracy of ±2°F or ±2% of the reading, whichever is greater.
Distance-to-spot ratio visualization: how measurement area changes with distance
Distance-to-Spot (D:S) Ratio
This ratio indicates how focused the measurement beam is. A 12:1 ratio means that at 12 inches away, the thermometer measures a 1-inch diameter spot. Higher ratios (like 30:1) allow for more precise measurements from greater distances, which is valuable when measuring hot or hard-to-reach surfaces.
Emissivity Settings
Emissivity refers to how effectively a surface emits thermal radiation. Different materials have different emissivity values. Basic models have fixed emissivity (typically 0.95), while advanced models allow adjustable settings for more accurate readings on various surfaces, especially metals and shiny objects.
Response Time
Most quality infrared thermometers provide readings in under a second. Faster response times are beneficial when you need quick measurements or are scanning multiple areas.
Laser Types
Single-point lasers show the approximate center of the measurement area. Dual-laser or circular laser systems provide a better visualization of the actual measurement area, improving accuracy and ease of use.
Display Features
Look for backlit displays for visibility in low-light conditions. Some models offer additional display features like maximum/minimum readings, average calculations, or high/low temperature alarms.
Durability
Consider the build quality, especially if you’ll be using the thermometer in demanding environments. Some models offer rubberized coatings for impact resistance or IP ratings for dust and water resistance.
Pro Tip: For most home cooking applications, a thermometer with a 12:1 D:S ratio, temperature range up to 750°F, and adjustable emissivity will provide excellent performance without breaking the bank.

Frequently Asked Questions About Infrared Thermometers
Can infrared thermometers measure body temperature?
Standard infrared thermometers designed for cooking or industrial use are not calibrated for medical purposes and should not be used to measure body temperature. Medical-grade infrared thermometers are specifically designed and calibrated for human body temperature ranges and have undergone FDA testing and approval.
How do I know if my infrared thermometer is accurate?
You can verify your thermometer’s accuracy using an ice bath test. Fill a container with crushed ice and add just enough water to fill the spaces between ice pieces. Let it sit for 3 minutes, then aim your thermometer at the surface (not at the ice directly) from the recommended distance. It should read very close to 32°F (0°C). For higher temperatures, you can test it against a known reliable thermometer or a calibration device.
Can infrared thermometers measure through glass or water?
No, infrared thermometers cannot measure through transparent surfaces like glass, plastic, or water. They will measure the temperature of the transparent surface itself rather than what’s behind it. For example, if you point an infrared thermometer at a pot of water through a glass lid, you’ll get the temperature of the glass, not the water.
What’s the difference between an infrared thermometer and a meat thermometer?
Infrared thermometers measure surface temperature without contact, while meat thermometers use a probe to measure internal temperature. For cooking meat safely, you need a meat thermometer to verify that the internal temperature has reached safe levels. An infrared thermometer can only tell you the external temperature of the meat, which doesn’t indicate doneness.
What is emissivity and why does it matter?
Emissivity is a ratio that specifies how being emissive an object can be. Also, it leads to calculating how much energy is emitted by an object. As a matter of fact, emissivity has a value of 0 to 1. Most infra-red thermometers come preset to 0.95, which is suitable for the majority of organic materials, food and non-metallic surfaces. To measure shiny metals accurately, a thermometer with adjustable emissivity will be required.
