Liquid Color Spectrophotometer ToronSpec™ TT-LC1

Parent Product

Liquid Color Spectrophotometer ToronSpec™ TT-LC1 is a high-precision spectrophotometer designed for accurate color measurement. It features a repeatability of ΔEab ≤ 0.015, ensuring consistent and reliable results. The inter-instrument agreement is excellent, with a ΔEab < 0.25, making it suitable for environments where multiple instruments are used and consistency across devices is crucial. The TT-LC1 model does not include a heating function, focusing instead on delivering precise color measurements without the need for temperature control.

Applications

The ToronSpec™ TT-LC1 is designed to provide objective, high-precision instrumental color analysis for a wide range of transparent liquids. It replaces subjective visual comparison methods with highly repeatable, numerical data, serving as a cornerstone for quality control, process monitoring, and ensuring products meet stringent industry-specific color standards.

This critical color measurement is essential for ensuring quality and consistency in:

Petroleum & Petrochemicals: For the quality assurance and refining process control of fuels, lubricants, and solvents, ensuring products meet specifications like Saybolt (for jet fuel) and ASTM D1500 (for lubricating oils).
Chemical Manufacturing: To control the purity and batch-to-batch consistency of resins, solvents, and polymers by precisely measuring color on scales such as Gardner and APHA/Pt-Co.
Pharmaceuticals: As a vital QC tool to ensure the purity, stability, and consistency of liquid drug products, APIs, and excipients in compliance with global Pharmacopoeia standards.
Food & Beverage: For monitoring and controlling the visual quality of products where color is a primary consumer indicator, such as in the sugar industry (ICUMSA) and brewing (EBC).
