HY-380 Multi-angle Gloss Meter is mainly used for surface gloss measurement of paint, plastic, metal, ceramics, building materials, textiles, paper, etc. This instrument complies with the following international and industry standards: ISO: ISO 2813; ASTM: ASTM D 523; JIS: JIS Z8741; DIN: DIN 67530; BS: BS 3900 Part D5. 1. High Precision a) Our gloss meters adopt top-tier sensors from Japan, high-end OP chips and processor chips from the US to ensure highly precise gloss measurement for each of your measured data. b) Our gloss meters conform to the JJG 696 standard for first-class gloss meters. Every machine has a metrology accreditation certificate issued by the State Key Laboratory of Modern Metrology and Testing Instruments and the Engineering Center of the Ministry of Education in China. 2. High Stability (Patent ZL2012201796876) a) Utilizing our patent-protected dual-light path technology, our gloss meters have a stability of 0.2GU. b) Each of our gloss meter instruments has undergone the following tests: c) 412 calibration tests; d) 43200 stability tests; i. 110 hours of accelerated aging test; ii. 17000 vibration tests. 3. Comfortable Grip 4. The shell is made of Dow Corning TiSLV material, a high-quality elastic material. It is UV-resistant, antibacterial, and generally non-allergenic, providing better user comfort. 5. Free APP 6. We provide a free App for easier data transmission and display, as well as the ability to view measured data at any time. 7. High Battery Capacity 8. We fully utilize every inch of space in the compact and comfortable instrument shell with a specially designed 4.4V high-density lithium battery, which has sufficient capacity to complete 54300 measurements before running out.
