Color tester

Introduction

A color tester is an instrument used to measure and evaluate the color of materials, such as liquids, solids, and powders, and it is used for quality control and color assessment in the paint, plastic, textile, food, and many other industries. The color tester measures the color of the sample by measuring the light reflected from or transmitted through the sample, and it calculates the color parameters, such as the L*a*b* values, the Hunter values, the whiteness, and the color difference from a standard, or it compares the sample with standard color scales, such as the Gardner and Saybolt scales for liquids; the color tester consists of a light source, a sample holder, a detector, and a control and display unit, and it provides an objective and reproducible measurement of the color, which is important for the quality control of products whose color is a quality attribute, and it may include features such as calibration with standard plates, the selection of color scales, and data management, and it is available as benchtop and portable instruments; the color tester is used for the color control of paints, coatings, plastics, textiles, foods, beverages, chemicals, and many other products, and it is used for the comparison of the color of samples with standards, for the assessment of the color difference, and for the monitoring of the color stability. Color testers are used in the paint and coating industry, in the plastic industry, in the textile industry, in the food and beverage industry, in the chemical industry, in the automotive industry, and for many other applications. With their objective color measurement, color testers are essential for color quality control.

Color Tester LCT-T2020

Color Tester uses an inside-frosted incandescent bulb as its light source. It operates at 220V with a color temperature of 2750 ± 50K. This provides consistent and standardized lighting...

FAQ

Q1: What scenarios is this tester used for?

A: It measures the color of oils, chemicals, foods or liquids on standardized scales using visual comparison or optical measurement for QC and specification.

Q2: What standards does it comply with?

A: It follows ASTM D1500 for petroleum color, related ISO and GB/T color methods, with standards and cells verified.

Q3: What is the warranty?

A: The tester carries a 12 to 24 month warranty covering the apparatus. Standards and cells are consumables. Damage from misuse is excluded.

Q4: Is it hard to operate?

A: Operation is simple after training: fill the cell, compare or measure and read the grade. We provide a manual and guidance.

Q5: What is the lead time?

A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Q6: Is calibration required?

A: We recommend verification against traceable standards at regular intervals, typically every 6 to 12 months, and keeping calibration records for audit purposes. The manual describes the procedure, and reference standards are available from us. Accredited third-party calibration can also be arranged on request.

Q7: Are consumables universal?

A: Color standards are certified and method-specific, while cells are standard. Ongoing cost includes standards.

Q8: Can it be customized?

A: Yes, several configurations are available. Options include visual or automatic measurement and multiple color scales. We can discuss further custom requirements, confirm feasibility and advise any effect on the schedule before the order is confirmed.

Q9: Is installation included?

A: No installation is required. The unit is delivered fully assembled and factory tested, so you only need to place it on a level surface, connect power and follow the quick-start guide. An illustrated manual and setup video are included, and our engineers provide remote guidance if needed.

Q10: What samples are compatible?

A: It handles clear liquids within the method. It is not for opaque or turbid samples without suitable instrumentation, non-liquid products, or colors outside the scale.
