Infrared Thermometer: How to Use for Enhanced Accuracy in Industrial Settings
Jan
Full Guide and Tips: How to Use An Infrared Camera
Temperature is a critical parameter in industrial processes and manufacturing, for obvious reasons.
Precise temperature control and measurement ensures product quality, operational efficiency, and safety. Infrared (IR) thermometers provide non-contact temperature measurement and are therefore widely used across industrial facilities.
However, proper techniques are required for accurate results. How you use infrared thermometers is crucial to the accuracy and consistency of your results.
This guide focuses on best practices for using infrared thermometers in industrial settings.
It covers the basics of how these devices work, steps for proper usage, applications in manufacturing processes, tips for professionals, and safety guidelines.

How to Use an Infrared Thermometer
1. Properly Prepare for Temperature Measurement
- Ensure a clear line of sight between the device and the target
- Set necessary parameters like emissivity
- Allow enough distance between the thermometer and the object
2. Follow Best Practices for Accurate Readings
- Hold the thermometer perpendicular to the surface
- Make sure the target area falls within the device’s spot size
- Take multiple readings in different areas for average values
- Avoid surfaces with high infrared reflectivity
- Ensure objects have reached thermal equilibrium
3. Avoid Common Mistakes
- Measuring through transparent surfaces like glass or plastic
- Not considering environmental factors like wind and moisture
- Neglecting emissivity changes from rust, residue or other alterations
4. Calibrate Your Infrared Thermometers
Periodic calibration ensures sustained accuracy.
- Calibrate against verified reference sources
- Adjust equipment to match standard values
- Log calibration data for traceability
At Process Parameters, we offer a professional temperature calibration service.
5. Interpret Your Data for Process Optimisation
- Log all measurements for historical records
- Identify patterns signalling problems
- Correlate data with other process parameters
- Quantify energy loss for upgrade justification
6. Use Proper Handling and Maintenance
- Avoid exposing the device to physical impact
- Keep lens clean and free of scratches
- Check battery indicator and replace as needed
7. Follow Safety Protocols in Industrial Environments
- Follow lockout procedures before equipment inspection
- Use appropriate personal protective equipment
- Measure dangerous objects like extremely hot materials with caution
Infrared Thermometers in Industrial Applications
Infrared thermometers instantly measure surface temperature from a distance. They detect infrared energy emitted from objects and convert readings into temperature values.
Industrial infrared thermometers feature durable designs for harsh environments. Different models offer various infrared spectral ranges, distance-to-spot ratios, response times and other features.

Importance of Accurate Temperature Measurement
Temperature affects chemical reactions, physical properties, and biological processes. Even small temperature variations in industrial settings can significantly impact product characteristics and plant efficiency.
By accurately measuring temperature, issues can be quickly identified and processes optimised. Infrared thermometers are thus vital for quality management.

Temperature Monitoring in Manufacturing Processes
Infrared cameras have many applications in manufacturing:
- Monitoring bearing and motor temperatures
- Scanning for overheating electrical systems and connections
- Spot-checking fluid tanks, pipes and vessels
- Mapping thermal distribution in ovens and furnaces
- Quality Control and Maintenance Applications
- Regular inspection of heat exchangers
- Identification of efficiency issues like steam leaks
- Post-maintenance verification of equipment
- Monitoring of critical zones in CNC machining
Basic Working Principle of IR Cameras
Infrared thermometers measure surface temperature without contact. The device optics focus infrared energy onto a detector, which generates signals based on the amount of radiation.
This data is converted into temperature readings using internal calibration algorithms. The results are instantly displayed.

Infrared Thermometer Usage Guide FAQs
How often should I calibrate my infrared thermometer?
We recommend calibrating your infrared thermometer every 6-12 months to maintain accuracy. Calibrate more frequently if the device is subjected to heavy use or extreme environments. Keep a log to track calibration history.
What is the best infrared thermometer for the food industry?
Look for infrared thermometers designed specifically for the food industry that meet regulatory standards. Ensure the device can handle high humidity environments and has the appropriate temperature measurement range and optical resolution for scanning cooked/prepared foods. Sanitary design is also an important factor.
Can infrared thermometers be used through glass or plastic?
Infrared thermometers measure the surface temperature of opaque materials. Readings through transparent surfaces like glass or plastic will measure the temperature of whatever is behind them instead. However, speciality infrared thermometers exist for low-emissivity surface measurement through transparent barrier films.
