Overview

Whiteness meter is a specialized instrument used to measure the surface color whiteness of grains and their products. It has a wide range of applications in food processing, agricultural research, quality inspection and other fields, especially playing an important role in the quality evaluation of grain products such as rice and wheat flour. By accurately measuring the whiteness value of grains, it can help production enterprises ensure consistency in product quality, meet market requirements for aesthetics and taste, and also assist scientific researchers in variety selection and processing technology optimization

Product Details

working principle

1. Light source illumination: Use standard light sources or similar artificial sunlight to simulate natural lighting conditions to ensure good reproducibility and comparability of measurement results.

2. Reflected light collection: After the sample is placed in the measurement window, the light shines on its surface and undergoes diffuse reflection; High sensitivity photoelectric sensors receive reflected light and convert it into electrical signals.

3. Data processing: The built-in microprocessor analyzes and calculates the received signal, and obtains the corresponding whiteness index according to internationally recognized standards.

4. The results show that the final whiteness value and related parameters can be clearly displayed to the user through the LCD screen, and some models also support printing output or data management through computer connection.

Product Features

1. High precision measurement: Advanced optical systems and precision calibration techniques are used to ensure the accuracy of each measurement result.

2. Quick response: The entire detection process can be completed in just a few seconds, improving work efficiency.

3. Multifunctionality: In addition to basic whiteness measurement, it can also provide multiple color indicators such as brightness and yellowness, comprehensively reflecting the color characteristics of the sample.

4. Easy to operate: The user-friendly interface and simple and intuitive operation process make it easy to get started without professional training.

5. Strong adaptability: Suitable for various shapes and sizes of grain particles and powdered products, both whole grains and crushed samples can be accurately measured.

6. Portable design: Small and lightweight, easy to carry to different locations on site or in the laboratory for use.

7. Durable and reliable: The shell and internal components are made of high-quality materials, which have strong anti-interference ability and are suitable for long-term stable operation.

Application field

1. Food industry: Quality monitoring of staple food raw materials such as rice and flour to ensure uniform and beautiful color of finished products.

2. Agricultural research: Evaluate the color performance of newly cultivated varieties, assist in crop improvement and planting structure adjustment.

3. Quality inspection: As an internal quality testing tool of the enterprise, it ensures that products meet established standards.

4. Trade circulation: plays a key role in the process of grain procurement and sales, helping buyers and sellers reach a mutually agreed price agreement.

5. Scientific research: Provide important experimental data support for fields such as food science and agriculture.

Purchase suggestions

1. Measurement accuracy: Determine the required low precision requirements based on actual needs, especially inIn the market, higher precision means more accurate results.

2. Applicability: Confirm whether the device can adapt well to the specific type of sample you are handling and the expected working environment.

3. Cost effectiveness: Taking into account performance indicators, brand reputation, after-sales service, and other factors, select valuable products within the budget range.

4. Technical support: Understanding whether suppliers can provide timely and effective technical support and services is crucial for later maintenance and problem-solving.
