Temperature control is one of the most critical aspects of running a safe and efficient commercial kitchen. Whether you’re preparing meats, baking pastries, or holding food for service, maintaining the correct temperature is essential for food safety compliance and quality assurance.
Two popular tools used by chefs and kitchen staff are infrared (IR) gun thermometers and digital probe thermometers. But which one is better for a commercial kitchen? Let’s compare their functions, benefits, and best uses to help you decide.
1. Infrared Gun Thermometer – Quick, Non-Contact Scanning
An infrared gun thermometer uses infrared technology to measure surface temperature without touching the food or equipment. It’s a fast, hygienic solution ideal for spot checks.
Benefits:
-
✅ Non-contact and hygienic – reduces risk of cross-contamination.
-
✅ Fast and convenient – instant readings, great for checking multiple trays or hot surfaces.
-
✅ Safe for hard-to-reach areas like grills, fryers, and ovens.
-
✅ Ideal for checking holding or surface temperatures of displayed food.
Limitations:
-
❌ Only measures surface temperature, not the internal temperature of food.
-
❌ Accuracy can be affected by steam, reflective surfaces, or incorrect distance-to-spot ratio.
-
❌ Not suitable for confirming safe cooking temperatures inside meat, poultry, or thick dishes.
2. Digital Probe Thermometer – Accurate Internal Temperature Reading
A digital thermometer with a probe is designed to measure the internal temperature of food. This makes it essential for ensuring meats, seafood, and baked goods reach safe cooking temperatures.
Benefits:
-
✅ Highly accurate – measures core temperature, crucial for food safety compliance (HACCP).
-
✅ Essential for meats, poultry, and high-risk foods.
-
✅ Versatile use – can be used for liquids, sauces, and baked goods.
-
✅ Many models are waterproof and quick-reading for fast kitchen workflows.
Limitations:
-
❌ Requires direct contact with the food, meaning probe cleaning between uses is necessary.
-
❌ Slightly slower than infrared for large batches.
-
❌ Not ideal for scanning hot surfaces or checking multiple trays quickly.
Which Is Better for a Commercial Kitchen?
Neither tool completely replaces the other—they serve different purposes:
-
Infrared Gun Thermometer: Best for quick surface checks, buffet service, checking hot-hold temperatures, or non-contact readings on griddles and fryers.
-
Digital Probe Thermometer: Essential for verifying internal cooking temperatures, ensuring compliance with food safety standards, especially for proteins and high-risk foods.
Professional kitchens should use both tools together:
-
Use an infrared gun for fast, hygienic surface checks.
-
Follow up with a digital probe thermometer for internal temperature verification before serving.
This combination helps you meet HACCP requirements, maintain food safety, and provide consistently high-quality dishes.

Final Thoughts
In a commercial kitchen, both infrared guns and digital thermometers play important roles.
-
Infrared guns: Quick, non-contact surface readings.
-
Digital thermometers: Accurate, internal temperature checks for food safety compliance.
For best results, invest in both types of thermometers to ensure accuracy, speed, and safe food handling throughout your kitchen operations.
