FAQs About  ISO Test Charts

They provide accurate and repeatable assessments of color in various settings for the purpose of avoiding inconsistencies in mismatched items and ensuring steady production or branding.


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


Daylight, store light, home light, and UV fluorescence light sources are included in Pantone light boxes as D65, TL84, CWF, A, and UV. 


When evaluating the accuracy of a colorimeter, repeatability is a key parameter. 

The repeatability standard deviation ΔE*ab of 3nh colorimeters is within 0.03 (measured under the following conditions: after preheating and calibration, measure the white calibration tile 30 times at 3-second intervals and take the average). This figure is superior to all other similar color measurement instruments. 

Each of our instruments undergoes rigorous factory inspection and calibration before delivery. In addition, 3nh colorimeters are guaranteed to pass the metrological certification issued by official metrology institutes.

To take care of a haze meter to make it last longer, ensure that it is cleaned, recalibrated regularly, and stored in a dry, dust-free place. 


Standard models are available in a range of sizes, starting from small desktop units which are roughly the size of 60 x 40 x 40 cm, and extending to larger units which are about 120 x 60 x 80 cm based on what you need them for.
