FAQs About NH300 Colorimeter


Colorimeter calibration is indispensable for reliable quality control—ensuring measurement accuracy by compensating for component aging, environmental interference, and baseline drift. It standardizes data across devices/batches, maintains compliance with industry standards, and prevents costly rework from inaccurate color readings, making it critical for precision-driven industries like printing, food, plastics, textiles, paint and coatings.

The photoelectric integral color‑measuring instrument is what we commonly refer to as a photoelectric colorimeter. It obtains color tristimulus values through one‑shot integral measurement, featuring fast measurement speed and low cost, yet its absolute accuracy is inferior to that of a spectrophotometer. It works well for quick color‑difference comparison. For sophisticated color analysis or color formulation, a spectrophotometer is recommended instead.

How it converts color into digital values

At its core, this type of instrument simulates human color vision. Filters work together with detectors to convert optical signals into electrical signals and then calculate numerical values.

  1. Light strikes the sample, and reflected light enters the instrument.

  2. Filters split the light into three channels: red, green and blue, corresponding to three photodetectors respectively.

  3. Detectors measure the light intensity of each channel. The instrument directly computes tristimulus values X, Y, Z as well as chromaticity coordinates.

  4. The matching performance of optical filters is critical. Better compliance with the Luther condition delivers higher measurement accuracy.

Differences from spectrophotometers

Both instruments measure color, yet they serve quite different application scenarios.

Photoelectric colorimeter: Simple structure, compact size and easy operation with fast measurement speed. It can only test color difference instead of spectrum, and its absolute accuracy is limited, with chromaticity‑coordinate error around ±0.03.

Spectrophotometer: Light is dispersed and measured wavelength‑by‑wavelength. It provides high accuracy (chromaticity‑coordinate error up to ±0.001‑±0.003) and can acquire spectral reflectance curves. However, it comes with higher cost, complicated structure and relatively slower measurement speed.

Suitable application scenarios

Photoelectric colorimeters are preferred for routine production inspection, quick comparison and cost‑sensitive projects.

  • Textile printing & dyeing: Rapid color matching and color‑difference comparison

  • Plastics, coatings and printing: Spot‑checking color consistency on production lines

  • Field‑testing scenarios: Handheld models support on‑site measurement

  • Budget‑limited projects: Photoelectric colorimeters are cost‑effective with sufficient practical functions


Threenh colorimters are used across various industries to measure, analyze, and control color accuracy and consistency:

Food and Beverages: Monitor color quality in food products to meet industry standards.

Plastics and Polymers: Ensure color uniformity in plastic components (e.g., casings, buttons, panels) during manufacturing.

Chemicals and Pharmaceuticals,Cosmetics: Industry-specific accessories to attain the highest safety protocols, Ensure uniform color in pharmaceutical products for quality and brand recognition;Develop and match colors for cosmetics (e.g., lipsticks, creams, powders) and ensure batch consistency.

Textiles and Apparel: Monitor color consistency in fabrics during dyeing, printing, or finishing processes; ensure color consistency in fabrics and garments.

Building materials, Paints, and Coatings: Detect color deviations in coatings on metal, wood, or plastic surfaces (e.g., automotive paints, furniture finishes). Maintain color accuracy in building materials, paints, and coatings.

Printing and Packaging: Validate color accuracy in printed materials (e.g., brochures, labels, packaging) against design proofs, maintain consistency across different printing technologies.

By addressing color-related quality control challenges, 3NH colorimeters help industries maintain brand consistency, meet regulatory standards, and enhance customer satisfaction.


Colors look different under various lights mainly because of metamerism—a phenomenon where two colors that match under one light source fail to match under another, caused by differences in the spectral composition of light.

object_Colors_look_different_under_various_lights1

Different lighting varies the color perception of objects. Warm light, like that from incandescent bulbs, tends to make colors more yellow, while daylight presents a bluish tint. Our color vision system plays a compensating role using a mechanism called color constancy.

Every light source emits light with a unique "spectral fingerprint" (i.e., the range and intensity of wavelengths it contains). This directly affects how an object’s surface reflects light and how our eyes perceive its color.
