Safety Notes:
- Operate within 15°C–40°C and <85% RH. Avoid condensation to ensure accurate gloss measurement.
- Allow the gloss meter to stabilize to ambient temperature before calibration and use.
- Keep away from strong electromagnetic interference sources.
- Do not force open the battery compartment during shutdown.
- Use high-quality batteries and dispose of them properly after use to ensure safe and long-term gloss meter operation.
- Avoid contact with strong solvents to prevent housing damage.
- Store in a dry place, away from heat and corrosive materials (-10°C to 60°C).
Applications

FAQs
Q1: What is the difference between gloss meter readings in GU and %?
A: Gloss Unit (GU) is the standard unit used in most gloss measurement applications, while % reflectivity shows surface reflection in percentage form. This digital gloss meter allows switching between both for flexible analysis.
Q2: Does this gloss meter require regular calibration?
A: No manual calibration is needed during daily use. The gloss tester features automatic self-calibration and self-diagnosis, ensuring stable performance and reducing maintenance workload.
Q3: What affects gloss meter accuracy during use?
A: Accuracy can be influenced by surface cleanliness, measurement angle stability, and environmental conditions. This gloss tester includes self-diagnosis to detect improper operation and ensure stable gloss measurement results.
