LX-A Shore Hardness Tester for routine measurement and teaching

The LX-A Shore Hardness Tester is a portable mechanical instrument for Shore A hardness measurement of medium- to low-hardness non-metallic materials. It measures the indentation response of rubber, plastic, polyester, leather, wax, and similar materials through a direct pointer display. Laizhou Jincheng Industrial Equipment Co., Ltd. provides this model for laboratories, educational settings, vocational training, and basic inspection tasks that require a clear, practical measurement method without a computerized data system.

Why laboratories and teaching users select LX-A

Visible testing principle: pointer reading helps operators observe how indenter penetration corresponds to a Shore A value.
Easy deployment: compact handheld construction supports use across classrooms, workbenches, incoming inspection areas, and production locations.
Practical comparison: suitable for routine checks and comparison of material samples with defined testing procedures.
Controlled loading option: an optional constant-load test stand can support more consistent positioning and applied load.

Measurement capability, operating conditions, and technical parameters

The LX-A is designed for direct mechanical testing within the Shore A scale. For reliable laboratory hardness testing, users should prepare a clean and reasonably flat sample, keep the instrument perpendicular to the test surface, and define reading time, measurement locations, and loading conditions according to the applicable material standard. Sample thickness, curvature, surface roughness, support condition, and material uniformity can influence results.

Direct pointer operation

No software setup is required. This supports hardness testing demonstrations where instructors and trainees need to understand the reading process directly.

Optional constant-load stand

The stand helps reduce variation from manual pressure and positioning, making it useful for comparative tests and repeated classroom exercises.

Standards-oriented use

Manufactured according to ISO 868 and ISO 7619, and meeting GB/T 531, JB 6148, and JJG 304 requirements; users should apply the relevant method for their material.
