How to Scientifically Choose a Thermal Imaging Camera?

As a key tool for non-contact temperature measurement, the selection of a thermal imaging camera needs to be based on a comprehensive consideration of actual application scenarios and performance parameters. This article uses core parameters as clues, combined with the technical characteristics of various products from FOTRIC, to provide a systematic purchasing guide to help users accurately match their needs.

Analysis of Core Parameters and Selection Logic

Temperature Range: The Foundation for Scenario Adaptation

The temperature range of a thermal imaging camera is one of the most fundamental and crucial parameters in the selection process. The required temperature range varies for different application scenarios, for example:

• Construction industry: Common temperature changes are relatively small, with a measurement range roughly between -20℃ and +100℃.

• Mechanical equipment and electrical inspection: Require a wider temperature measurement range, usually between -40℃ and +150℃ or even higher.

• High-temperature industrial applications (such as metallurgy, ceramics, etc.): Have stricter requirements for high-temperature detection, with a measurement range possibly needing to reach -50℃ to +1500℃ or higher.

Scenario-based Product Recommendations

Industrial Equipment Maintenance

Power inspection: FOTRIC 3 5 0+ series equipped with "automatic temperature rise calculation" function, one-click diagnosis of electrical equipment overheating, reducing manual errors.

Petrochemical explosion protection: FOTRIC860-Ex series certified by Ex ib IIC T4 Gb, suitable for flammable and explosive areas in Zone 1/2, balancing safety and detection efficiency.

Scientific Research and Precision Testing

Material thermal analysis: FOTRIC 240M series thermal imaging cameras can run in online mode for a long time, with 1TB single video storage capacity meeting long-term experimental data recording needs.

Microelectronics research: FOTRIC 288+ scientific thermal imaging camera combined with 20μm lens, 640 × 480 infrared pixels and about 20 mm test distance, can capture the thermal distribution of chip solder joints.

Selection Decision Process

1. Clarify the priority of needs: Differentiate between handheld or fixed, detection distance, accuracy requirements, and initially lock in the product line.

2. Parameter matching: Choose resolution and lens according to target size (formula: minimum target = distance × IFOV).

3. Functionality: Temperature rise alarm, full radiation video recording, regional emissivity settings, macro lens, etc.

4. Budget balance: Comprehensive consideration of technical selection and cost control.
