Electronic Hardness Tester
Two Models for Soft and Hard Materials
Our company has 17 years of experience in manufacturing testing equipment. We are located in Jiangdu District, Yangzhou, Jiangsu Province, and operate a 1,000 sqm workshop with 10 workers.
This hardness tester is available in two models: LX-A and LX-D. Each model is available in both dial and digital versions, allowing selection based on user requirements.
The LX-A model is designed for soft materials, while the LX-D model is designed for hard materials.
The LX-A rubber electronic hardness tester is used to measure the hardness of vulcanized rubber and soft plastics. It complies with GB 527, GB 531, and JJG 304 standards.
It can be used for laboratory testing of standard samples or handheld testing of rubber components on equipment.

Easy to Use and Portable
The LX-A electronic hardness tester has a press pin stroke range of 0–2.5 mm.
The dial scale range is 0–100 (no unit). The indenter tip force ranges from 0.55 N to 8.06 N (56–822 g).
The LX-D electronic hardness tester is designed for high-hardness materials such as hard rubber, hard resin, acrylic, glass, thermoplastics, circuit boards, and fiber materials.
It complies with GB/T 531.1-2008 standard.
The dial type provides clear and accurate readings.
The instrument features a handheld design for easy portability. It can be used either handheld or mounted on a test stand.
- Measurement range: 0–100
- Recommended measurement range: 10–90
- Dimensions: 115 × 60 × 25 mm
- Press pin stroke: 2.5 mm
- The LX-D model uses a conical indenter.
