Liquid Color Spectrophotometer ToronSpec™ TT-LC2

Liquid Color Spectrophotometer ToronSpec™ TT-LC2 is a versatile spectrophotometer equipped with a heating function, allowing it to operate at temperatures ranging from ambient up to 90°C. This feature makes it suitable for applications requiring temperature-controlled environments. The Liquid Color Spectrophotometer ToronSpec™ TT-LC2 model offers superior repeatability with ΔEab ≤ 0.01, ensuring high precision in color measurements. Its inter-instrument agreement is also very reliable, with a ΔEab < 0.2, making it a strong choice for settings where multiple instruments are used and consistent performance is required.

The ToronSpec™ TT-LC2 is specifically designed for the high-precision color measurement of liquids that are solid, semi-solid, or highly viscous at ambient temperatures. Its integrated heating function (up to 90°C) provides precise temperature control, eliminating the need for external water baths and ensuring that samples are measured in a consistent, fluid state for maximum accuracy and repeatability.

This temperature-controlled analysis is critical for quality control in:

  • Edible Oils & Fats: For the essential color grading of products like palm oil, coconut oil, tallow, and shortening, which must be melted to a clear liquid to accurately assess quality and refining levels.
  • Waxes, Resins & Polymers: To perform quality control on materials like paraffin wax, rosins, and various industrial resins that require heating to a molten state for a true and consistent color measurement.
  • Chemicals & Fatty Acids: For purity and quality assessment of high-viscosity or solid organic chemicals, such as fatty acids, that must be liquefied at a specific temperature to ensure accurate and repeatable color analysis.
  • Asphalt & Bitumen: To measure the color of binders and heavy petroleum products at elevated, standardized temperatures, providing a key quality metric related to material sourcing and aging.
