IdealPhotonics' thermal sensing card is a tool that visualizes temperature distribution using thermosensitive materials (such as liquid crystals or infrared dyes). It displays color changes within a specific temperature range (e.g., 30-120℃) for rapid detection of the surface thermal field distribution of electronic components, mechanical equipment, or biological samples.Parameters including temperature response range (e.g., 30-120℃), sensitivity (±1℃), color contrast (ΔE>5), response time (<10s), and durability (reversible type >100 cycles) directly determine its accuracy and practicality in temperature detection.
