The TLC-100 spray-on liquid crystals are designed for heat transfer studies and mapping heat fields on electronic components or boards. The crystals change color at a specified temperature starting at red, changing to green then blue. For electronics cooling applications, this provides the user accurate information about the location of hot spots on a device, their temperature and temperature gradient.
To map the temperature profile of a component or board, black ink is airbrushed on to the specimen. Then the liquid crystals, with a temperature range depending on the application, are sprayed onto the measurement surface. The thermochromic liquid crystals are available in a variety of temperature ranges from 12° to 120°C, each one has a particular bandwidth from 1°C to 20°C. Hotspot locations can be confirmed and changing temperatures can be seen at various current output levels. ($761.87 ea — available now.)
