Overview
JND-A60 Glossiness Meter is a JND brand High Accuracy General Glossiness Meter. It is designed and manufactured with reference to international standard ISO 2813 and Chinese national standard GB/T9754. The technical parameters comply with ASTM D2457, ASTM D523 and GB/T13891, GB/T7706, GB/T8807 standards. The instrument performance indicators meet the requirements of the second-level working machine in the national standard JJG 696-2002 Measurement verification procedure. Traceability of Gloss value can be obtained from the gloss benchmark of Shanghai Institute of Measurement and Testing Technology (SIMT).
Features
1. Automatic High Accuracy, High stability, Instant test, Simple and convenient operation.
2. Traceability of measurement data to the "SIMT" National Measurement verification center through trusted certification for five consecutive years.
3. National first-class standard black (high) white (low) calibration plate, in line with national standards, can easily pass Measurement verification.
4. Adopt professional optical path design, stable and reliable measurement data, minimal Inter-instrument Agreement and excellent reproducibility.
5. Ergonomic shell, high-end mold one-time molding, anti-skid, light, and can resist a variety of solvents.
6. Pay attention to safety with high-end nonconductive shell, high safety factor, to avoid electric shock.
7. Built-in rechargeable battery pack, the power supply adopts imported high-end management chip, and the measurement can last for more than 48 hours after being fully charged.
8. Adopt imported non-mechanical three-proof power switch, which has a long lifespan and a good feel.
9. Elliptical angle, soft surface probe design, effectively prevent the measurement process from scratching the measured object.
Principle
JND-A60 Glossiness Meter is designed with professional optical path, using elliptical shape measurement port and 36 * 18mm Measuring Area under 60 ° Measurement Angles to carry out gloss measurement on the surface of the object. The instrument adopts High Accuracy Sensor and stability circuit to ensure reliable data, and realizes auto calibration through built-in calibration plate, which meets international and domestic standards.
Applications
Gloss measurement of inks, coatings, paints, varnishes and other surface Gloss measurement, building decoration materials: Stone, Pottery and porcelain, ceramic tile, marble, vitrified polished tiles and other surface Gloss measurement, printing, bamboo and wood products, fabrics, film paper, plastics and other surface Gloss measurement, rubber, leather, automobile maintenance and other surface Gloss measurement, other Non-metallic materials Surface Gloss measurement
