1. APPLICATIONS & FEATURES

* Whiteness Meter is mainly used to directly measure the whiteness value of object or powder with flat surface.

* Can be widely used in whiteness measurement of textile printing and dyeing, paint, chemical building materials, paper board, plastic products, white cement, ceramics, enamel, talc powder, starch, flour, salt, detergent, cosmetics and other substances.

* It consists of Light Source, Optical System, Detection System, Data Process and Display System. The whiteness Calculation Formula of the instrument is blue light whiteness R457.

* Use of high quality imported components, good reliability.

* The optical path design is reasonable, simple. Adopt filter system with correction, the whiteness can be reflected quantitatively.

* No preheating after starting, measurements can be taken after simple calibration, easy to operate.

* Able to memory 254 groups of measurement data.

* Use USB data output and RS-232 data output to connect with PC.

* Provide Bluetooth data output choice.

1. OPERATING PRINCIPLE The light source of the instrument is long-life LED with 457nm, conforming to the light source requirement in the JJG 512-2002 National Metrological Whiteness Meter Verification Regulation. The measurement of the instrument adopts the principle of photoelectric effect. The diffuse reflectance Radiant Brightness Energy Value of the sample surface is receive by the optical cell. Then, the value is amplified by high-precision auto

zeroing operation amplifier, inputted to the calibration circuit for energy calibration. Then, the whiteness value of the sample is directly shown on the digital display.

3. NOTE

This instrument is a metrological appliance, is strictly forbidden to disassemble. please read the instructions carefully before use.

* There should be no corrosive gas or vibration source in the operating environment.

* There should be no light exposure and magnetic field interference.

* The ambient air should be dry and no dust, etc.

* If the instrument is not to be used for any extended period, remove batteries to prevent battery leakage corroding internal circuit.

* To keep the measuring sensor clean, not to touch the optical element with hand, so as not to affect the spectral characteristics.

6. MEASUREMENT PROCEDURE

6.1 Important Notice

6.1.1 Before using the instrument, it is necessary to carefully read the manual, and operate in strict accordance with the stipulated working conditions and usage methods.

6.1.2 The standard white board is used for calibration of the instrument. It is necessary to keep the surface clean with no exposure to dust. Avoid artificially affecting its nominal value.

6.1.3 Keep the optical components of the instrument clean, do not rub or touch

6

them with hands. If there is dust on optical components, use wash ear ball to blow off dust on the surface or wipe with lens wiping paper. If there is oil or mildew on optical components, use absorbent cotton dipped in absolute alcohol to wipe the surface. When the instrument is not to be used for any extended period, sheathe it in a dust cover, which is self-made.

6.1.4 Before starting up, clean the measuring aperture with optical cleaning cotton cloth. In order to avoid contamination of the whiteboard and test samples.

6.1.5 Test sample surface should be flat or even. The consistency of the longitudinal and transverse directions of the tested samples should be maintained in the repeatability test. For samples without flat or even surface(such as powder, particles, fiber), it is necessary to prepare a sample board. For details see 6.2 Sample Preparation.

one. The instrument can store up to 254 groups of data.

6.4.2 To browse the stored data, just press the Read/Plus Key, the Measurement Symbol disappears on the display, while the Reading Symbol appears, indicating it is in browsing state. Press the Read/Plus Key or Minus Key to browse the data in the instrument.

6.4.3 To quit browsing state, just press the Power Key.

6.5 Data Deleting There are two ways to delete the data, single delete and delete all.

A. Single data can be deleted in the browsing state. Press Read/Plus Key or Minus Key to call out the data to be deleted, press the Delete Key, the current data is immediately deleted. After deleting the last group of data, Err1 is displayed on the screen, which indicates that all the data has been removed.

B. To move all the data, just press and hold the DEL delete key for about 3

6.2.1 If the uneven surface of the sample can not be improved, or there are difference between the horizontal textures and vertical textures, measure the sample at different positions or angles, adopt the average whiteness value as the whiteness value.

6.2.2 For paper, cloth and various fiber fabric, it is necessary to overlap them till opaque. If the whiteness value does not change when increasing the number of samples, it is opaque.

6.2.3 For powder or small granular samples, shall be put in powder containers, flatten with bright and clean glass plate. Different preparing conditions bring different test results, so, in order to establish the whiteness relationship between the same kind of samples, the preparing method must be unified, including weight, particle size and pressing method. So that the samples have approximate density and surface roughness. If higher accuracy is required, adopt the constant pressure
