Datacolor Check is a high-performance, mobile spectrophotometer equipped with flexible and convenient features of contemporary PDA equipment. It is suitable for various industries and surfaces for sample color measurement. It can help you to innovate more quickly, ensure consistent color quality, reduce production costs and accelerate the speed of product listing.

Instrument Introduction [Download Samples]

Check series portable color meter, the latest product of Datacolor Company, is a unique product manufactured with the latest hardware and software technology, which combines a lot of advantages.

Check is a comprehensive and versatile tool that reflects laboratory level requirements on hand-held color meters. Make it easy for you to perform color detection, evaluation and control on the production site or in the laboratory.

Check, like Datacolor's precision desktop computer, is an integral sphere, double-beam measuring principle, pulsed xenon lamp source, ultra-high precision SP-2000 photoelectric analyzer, so it has high accuracy and long-term stability, and the best data compatibility.

New user interface:

Check uses PDA as its user interface and Palm as its operating system. So it has the following new characteristics:

Large area, high resolution, high contrast screen; all relevant data are displayed on the screen.

Touch operation, gently, all kinds of functional menu options at a glance. It is easy to operate and use.

Click or hand-write the name of the color sample to facilitate data management and retrieval (the instrument has data retrieval function).

It is equipped with 32M "data backup flash card", which can backup data at any time to prevent loss.

Gloss compensation measurement mode:

Based on the traditional SCI/SCE (Automatic Gloss Inclusion/Non-Inclusion) measurement mode, a new "Gloss" measurement mode is added. When the mode is activated, it has the following special functions:

1. Measure the gloss value of three angles (20/60/85) of the color sample.

2. When the gloss of standard and contrast samples is different, the instrument will prompt automatically.

3. For two color samples with different gloss, the color difference after gloss compensation is given. Compared with SCI/SCE mode, this color difference value can correctly reflect "the real visual difference between two colors".

Powerful data retrieval function:

1. Input the approximate name of the color sample and search the target.

2. Input the chroma value of the color sample (measure the color sample or input value), search for the nearest color!! (This function can greatly speed up color matching: first, the customer samples are measured, then the instrument searches for the closest color matched before, and gives the color difference, then adjusts on the basis of the color formula.)

Print measurement results:

It can be connected to a micro printer to print the measurement results in real time.

Data transmission and management software:

Random equipment for data transmission to the computer, and further processing of data. The limited storage capacity of the instrument can be extended to infinity.

Connect powerful color measurement and quality management software:

Optional purchase of the software, and instruments constitute a "quality management system".
