Portable Shore A hardness testing for routine plastic quality checks

The LX-A Shore Hardness Tester is a lightweight handheld mechanical durometer for measuring suitable medium- and low-hardness plastic materials and parts on the Shore A scale. Developed by Laizhou Jincheng Industrial Equipment Co., Ltd., it uses an indentation-based method and a direct pointer display to support quick hardness comparison in receiving, production, warehouse, laboratory, and teaching environments.

Where it fits in the inspection process

Incoming material inspection: compare raw materials, semi-finished products, or purchased parts against defined supplier or internal requirements.
Production sampling: carry out periodic checks near the production line without moving every sample to a fixed laboratory.
Parts quality control: assess suitable plastic sheets and components alongside part design, thickness, and acceptance criteria.
Field and warehouse checks: use the compact instrument where a fast, portable comparison tool is needed.

Application boundary: The LX-A is intended for applicable Shore A materials and reasonably suitable test surfaces. Surface roughness, curvature, sample thickness, support condition, material uniformity, and operator technique can affect readings; users should establish consistent sampling locations and procedures before routine inspection.

Mechanical operation, controlled testing options, and key specifications

The LX-A combines a simple handheld body with visible mechanical pointer reading. During testing, the indenter is placed vertically on a clean, adequately supported surface and read according to the applicable test method. This straightforward approach helps quality teams make direct batch-to-batch comparisons while keeping the instrument easy to deploy across different work areas.

Direct mechanical reading

The pointer-type display provides immediate Shore A readings for routine checks, material demonstrations, and basic laboratory measurements without a complex operating interface.

Optional constant-load test stand

Where manual loading variation needs to be reduced, an optional test stand can provide a more stable loading arrangement and support more consistent comparison conditions.

Portable inspection format

At approximately 160 g, the handheld Shore durometer can move between receiving areas, production stations, warehouses, and customer sites for practical on-location testing.
