Haze Meter is an instrument specially used to detect the haze and transmittance of transparent or translucent materials. The haze meter needs to meet the corresponding standards, so the test results can be accepted by the public. Today, we mainly introduce the ASTM standard of Haze Meter.
What is the ASTM standard and what is its use?

ASTM American Society of testing materials was formerly known as the International Association for testing materials (IATM). After a century of development, ASTM now has 33669 (individual and group) members. Its main task is to formulate characteristic and performance standards, test methods and procedure standards in the fields of materials, products, systems and services, and promote the development and promotion of relevant knowledge.
ASTM standards are represented by standard code + letter classification code + standard serial number + formulation year + standard English name.
(1) If there is a letter M after the standard serial number, it is the metric unit standard, and if there is no letter M, it is the British unit standard.
(2) If there is a bracket after the formulation year, the year in the bracket indicates the year when the standard was re approved.
(3) If there is a, B, C.... After the formulation year, it indicates the revision of the standard.
(4) If there is £ 1, £ 2, £ 3,... After the formulation year, it indicates the number of times that the standard is only subject to editorial modification without substantive content modification
(5) Meaning of letter classification code:
A - ferrous metal
B - non ferrous metals
C - cement, ceramics, concrete and masonry materials
D - other materials (petroleum products, fuels, low strength plastics, etc.)
E - Miscellaneous (metal chemical analysis, fire resistance test, nondestructive test, statistical method, etc.)
F - special purpose materials (electronic materials, shockproof materials, medical and surgical materials, etc.)
G - corrosion, deterioration and degradation of materials
ASTM standard has customized a unified standard for the detection in the field of object color, and solved the disputes about material specifications, test procedures and so on.
The product of Hangzhou color spectrum technology, ASTM standard haze measuring instrument cs-720, is an instrument for measuring haze that strictly abides by and supports ASTM standards. In addition to measuring haze transmittance, it also has a big trick, color measurement, which is not at first glance
Serious Hazemeter! Less nonsense, let's quickly introduce this ASTM standard haze measuring instrument to you!
1、 Introduction to ASTM standard haze measuring instrument cs-720
1. At the same time, ASTM and ISO haze measurement standards are followed to provide a, C and D65 measurement light sources for haze measurement

2. It can realize the compensation measurement of transmittance and provide more accurate transmittance test results for haze measurement

3. Color spectrum Haze Meter cs-720 provides a powerful color measurement function. It has the most complete measurement indicators and measurement light source in the industry. Haze color measurement can be carried out at the same time

4. The open measurement area liberates the limitation of sample size, and you can even measure vertically

5. Provide abundant fixtures to meet the measurement needs of different forms of sheet and liquid samples

6. Color spectrum Haze Meter cs-720 can not only measure haze transmittance color, but also provide color and transmittance measurement and analysis software to meet the user's analysis and management of test data, which can be stored
