HY-300 Single-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 Z8741JJG696; DIN: DIN 67530; BS: BS 3900 Part D5. 1. High Precision a) Our gloss meters use top-of-the-line sensors from Japan, high-end OP chips and processor chips from the US to ensure highly precise gloss measurement for every piece of your measured data. b) Our gloss meters conform to the JJG 696 standard for Class 1 gloss meters. Every machine has a metrology accreditation certificate from 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) Using our patent-protected dual light path technology, our gloss meters have a stability of 0.2GU. b) Every one of our gloss meter instruments has undergone the following: c) 412 calibration tests; d) 43200 stability tests; i. 110 hours of accelerated aging test; ii. and 17000 vibration tests. 3. Comfortable Grip 4. The hull is made of Dow Corning TiSLV material, a desirable elastic material. It is resistant to UV and bacteria and usually does not cause allergies, for better user comfort. 5. Free APP 6. We offer 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 utilized every inch of space in the neat and comfortable instrument hull with a specially designed 4.4V high-density lithium battery, which has enough battery capacity to complete 54300 measurements before the battery runs out.
