In the papermaking, packaging, and printing industries, paper thickness is one of the core indicators of product quality. According to a market research report by QYResearch, the global paper thickness tester market reached USD 171 million in 2024 and is projected to grow to USD 247 million by 2031. As quality control requirements become increasingly stringent, high‑precision and intelligent thickness measuring instruments are becoming standard equipment in laboratories and production lines.

The YT‑H4E Paper Electronic Thickness Tester strictly complies with multiple national and international standards, including GB/T 451.3, QB/T 1055, GB/T 24328.2, and ISO 534. It is suitable for measuring the thickness of various types of paper and other sheet materials, and is widely used in paper mills, research institutes, and quality inspection departments.

In terms of core performance, the YT‑H4E offers a measuring range of (0–5) mm with a resolution of 0.001 mm, enabling accurate capture of micron‑level thickness variations. The indication error is ±0.0025 mm or ±0.5 %, repeatability is ≤0.0025 mm or ≤0.5 %, parallelism between measuring faces is ≤0.005 mm, contact area is (200±5) mm², and contact pressure is (100±10) kPa – all technical indicators reaching the industry’s leading level.

The YT‑H4E is powered by a Cortex‑M4 ARM processor, ensuring fast response and precise calculations. Its 7‑inch IPS high‑definition capacitive touch screen offers a smooth operating experience. One‑key testing and adjustable measuring head descent speed (0.5–10 mm/s) make routine testing more efficient and convenient. The instrument also features power‑off data preservation, automatic measurement, statistics and printing, and USB data export. It supports multiple communication methods including WiFi and USB, and test data can be uploaded to cloud servers. When used with the QMS paper quality management system, it enables real‑time monitoring and traceability of test data.
