Precision Meets Versatility: Introducing the CHY-CA Thickness Tester for Advanced Material Quality Control

A New Benchmark in Mechanical Contacting Measurement

The CHY-CA thickness tester is engineered around the mechanical contacting thickness gauge principle, a time-tested methodology that delivers unparalleled repeatability and accuracy. As a fully compliant ISO 4593 film thickness tester, the instrument is purpose-built for determining the thickness of plastic films and sheeting by mechanical scanning — the gold standard method recognized by international regulatory bodies.

Unlike non-contact alternatives that can be affected by material opacity, surface reflectivity, or environmental interference, a mechanical contacting thickness gauge provides direct, traceable measurements. This makes the CHY-CA thickness tester the preferred choice for quality assurance professionals who cannot afford ambiguity in their data.

Uncompromising Performance as a Plastic Film Thickness Gauge

When configured as a plastic film thickness gauge, the CHY-CA delivers exceptional specifications:

• Test Range: 0–2 mm (standard), with optional extensions to 6 mm and 12 mm

• Resolution: 0.1 μm — capturing minute thickness variations invisible to lesser instruments

• Test Pressure: 17.5±1 KPa for films, 50±1 KPa for paper, with a contact area of 50 mm² (film) or 200 mm² (paper)

• Test Speed: 10 measurements per minute, adjustable to match workflow requirements

• Specimen Feeding: Programmable interval from 0 to 1000 mm with feeding speed from 0.1 to 99.9 mm/s

These specifications position the CHY-CA thickness tester as a versatile digital thickness measuring instrument suitable for a remarkably wide range of materials — from ultra-thin plastic films and battery separators to paper, foils, non-woven fabrics, and silicon wafers.

Built for the Standards-Driven Laboratory

In regulated industries, compliance is not optional. The CHY-CA thickness tester is designed and calibrated to conform to an extensive portfolio of international standards, making it a true ISO 4593 film thickness tester alongside comprehensive support for:

• ISO 4593, ISO 534, ISO 3034

• ASTM D374, ASTM D645, ASTM D1777

• TAPPI T411

• GB/T 6672, GB/T 451.3, GB/T 6547

• DIN 53105, DIN 53353

• JIS K6250, JIS K6783, JIS Z1702

• BS 3983, BS 4817

This breadth of compliance means a single CHY-CA thickness tester can serve laboratories that report to multiple regulatory frameworks — eliminating the need for redundant equipment and simplifying audit readiness.

Intelligent Automation for High-Throughput Environments

What sets this digital thickness measuring instrument apart from conventional gauges is its intelligent automation capability. The CHY-CA thickness tester features:

• Automatic presser foot lifting and lowering — reducing operator fatigue and eliminating inconsistent manual handling

• Automatic specimen feeding — programmable step distance and speed for unattended batch testing

• Dual-mode operation — manual mode for spot checks, automatic mode for high-volume quality control

• Real-time statistical analysis — instant display of maximum, minimum, average, and standard deviation across up to 100 measurement points per group

• 500-group data storage with audit trail and multi-level user permission management

• RS232 and network interface — supporting centralized data management across LAN and internet

These features transform the CHY-CA thickness tester from a simple plastic film thickness gauge into a comprehensive quality data management station.

Why Choose a Mechanical Contacting Thickness Gauge?

In an era of optical and laser-based measurement technologies, the enduring relevance of the mechanical contacting thickness gauge deserves explanation. While non-contact methods have their place, a dedicated film thickness tester based on the contacting principle remains irreplaceable for standardized quality assurance. The answer lies in fundamental physics: a contacting method measures the actual material thickness under a defined pressure, exactly replicating the conditions specified in international standards.

For materials where compressibility matters — such as non-woven fabrics, paper, and certain polymer films — a non-contact method may report thickness at zero pressure, yielding values that differ from standardized test conditions. A properly calibrated plastic film thickness gauge using the contacting method eliminates this discrepancy entirely. The CHY-CA thickness tester, as an ISO 4593 film thickness tester, applies the exact pressure prescribed by the standard, ensuring that measurements are not merely precise but also legally defensible and commercially comparable.

Applications Across Industries

The versatility of the CHY-CA thickness tester as a digital thickness measuring instrument makes it indispensable across multiple sectors. Whether deployed as an ISO 4593 film thickness tester in a packaging lab or as a general-purpose film thickness tester on a production floor, it delivers consistent, audit-ready results:

• Flexible Packaging: Quality control of plastic films, laminates, and barrier materials

• Battery Manufacturing: Precision measurement of separator films where micron-level accuracy directly impacts cell performance and safety

• Paper and Paperboard: Thickness measurement per ISO 534 for packaging, printing, and specialty papers

• Medical Device: Thickness verification of medical films, membranes, and sterile barrier materials

• Electronics: Silicon wafer and thin-film substrate measurement

• Textiles: Non-woven fabric thickness testing for filtration, hygiene, and industrial applications
