🔍 Introduction

Thermometers are everywhere—from the kitchen to the clinic, and even your toolbox. But with the rise of infrared (IR) thermometers, many users are asking:

“Do I really need an infrared thermometer, or is a traditional one enough?”

Let’s break down the pros, cons, and use cases of both to help you choose the right tool.


🧪 What Is a Traditional Thermometer?

A traditional thermometer includes:

  • Mercury/Alcohol-based analog models

  • Digital contact thermometers (with metal probe or sensor)

These devices require physical contact with the surface or body to measure temperature.

✅ Common Uses:

  • Taking body temperature

  • Cooking (with probe thermometers)

  • Lab and clinical use


🔥 What Is an Infrared Thermometer?

An infrared thermometer uses infrared radiation to measure surface temperature without touching the object.

By simply aiming the device at a target and pressing the trigger, you get an instant temperature reading.

✅ Common Uses:

  • Cooking (surface and grill temps)

  • Electrical/electronics diagnostics

  • HVAC and industrial systems

  • Non-contact fever screening

  • Automotive temperature checks


🆚 Comparison: Infrared vs Traditional Thermometer

Feature Infrared Thermometer Traditional Thermometer
Contact Required ❌ No ✅ Yes
Speed ⚡ Instant (<1s) 🕒 5–30 seconds
Safety (High Heat) ✅ Safe from a distance ❌ Potential burn risk
Accuracy (Body) Moderate (±0.5°C typical) High (±0.1–0.2°C)
Accuracy (Surface) ✅ Excellent ❌ Often not suitable
Best For Surfaces, industrial, food Medical, lab, core body readings
Limitations Affected by reflectivity/emissivity Needs full contact, slower

 


🔧 Use Case Scenarios

🔹 For Fever or Medical Use:

  • Traditional Digital Thermometer is more accurate for internal or underarm temperature.

  • Infrared Thermometers (forehead type) are great for quick, non-contact screening.

🔹 For Cooking:

  • Infrared Thermometers are ideal for checking pan, grill, or oil temperatures

  • Use traditional probe thermometers for internal meat temps

🔹 For Electrical or HVAC:

  • Infrared Thermometers help you detect overheating components without opening panels or making contact.

🔹 For Industrial Safety Checks:

  • Use IR thermometers to scan motors, transformers, and machinery from a safe distance.


🏆 Recommended: BSIDE Infrared Thermometers

If you're looking for an accurate and affordable infrared thermometer, BSIDE offers several models tailored for both personal and professional use:

🔸 BSIDE AD-650 Infrared Thermometer

  • Instant readings from -50°C to 650°C

  • Adjustable emissivity for different surfaces

  • Built-in laser pointer for targeting

  • Lightweight and ergonomic

🔸 BSIDE S7 Pro (with multimeter)

  • Combines infrared thermal detection with smart multimeter functions

  • Ideal for electricians and HVAC technicians


✅ Conclusion: Which One Should You Use?

Use Case Recommended Thermometer
Check body fever Digital contact thermometer
Quick surface scan Infrared thermometer
Grill, stove, or frying Infrared thermometer
Meat internal temp Traditional probe thermometer
Electrical diagnostics Infrared thermometer
Medical/lab use Traditional thermometer

 

Bottom Line:
If you need quick, hands-free temperature readings—especially for surfaces or dangerous environments—go infrared. For internal body temperature or precise medical readings, stick with traditional contact models.
