INTRODUCTION

MEWOI-XSB-1Y Whiteness Meter is mainly used to 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, paperboard, plastic products, white cement, ceramics, enamel, talc powder, starch, flour, salt, detergent, cosmetics and other substances.

MAIN FEATURES

1,aluminum box , easy to carry, suitable for field testing of samples.

2,adopt original imported components, high efficiency, low loss switching power supply reliability.

3,efficient light source system to measure times of up to 200,000 hours, no need to replace the light source.

4,reasonable, simple optical design, using the revised color system that can quantitatively reflect the fluorescent whitening whiteness after.

5,using 45/0 observation conditions can eliminate the influence of the measured object due to surface gloss whiteness values.

6,reliable sealing platform design, can effectively prevent light leakage measurement orifice.

7,micro-power design, five AA batteries   (not included)    can be used more than six months.

8,test speed, 1 second to complete a measurement operation.

9,easy to operate, can accurately measure the opacity of paper
10,measurement data is stable and repeatable.
11,intelligent memory system, after the instrument after initial setup, when the general measurement no longer be zero adjustment and white calibration.
12, instrument has an automatic power saving features, without any action after the instrument is turned on, automatically shut down after 15 minutes.
13,measurement operation error alarm.
14,use of national calibration standard whiteboard to deliver value, accurate and reliable measurements.
15,low battery indicator function, when the battery is exhausted can prompt the user to replace the battery, in order to ensure accurate and effective measurement operations.

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.
