Rubber hardness tester

1、 Overview:

JR-M-IRHDRubber hardness testerUsed to measure the conventional hardness of rubber and similar rubber material test pieces and specimens. It is a device that implements the GB/T6031-M standard for the determination of hardness (30-85IRHD) of vulcanized rubber using micro tests.

Through the precise coordination of high-precision transmission system and sensing system, a single test is automatically completed under the control of the system. In addition to measuring the hardness of standard rubber test pieces, it can also measure the apparent hardness of small volume finished parts, especially suitable for measuring the apparent hardness of O-rings and non-destructive apparent hardness measurement of small parts remaining from damaged parts.

2、 Main features:

1JR-M-IRHDRubber hardness testerUsing laser point finding technology is more suitable for detecting O-rings. The device will automatically locate the high point of the O-ring's cut surface and send it below the measuring head to complete the hardness test automatically.

2. Adopting a touch integrated operating system, the interface is intuitive and generous, making it easier to operate.

3. German imported servo system with precise positioning to ensure accurate measurement.

4. Equipped with a built-in micro printer, each sample supports 5 output points.

3、 Main technical indicators:

1. Contact force: 8.3 ± 0.5mN

2. Compression force: 145 ± 0.5mN

3. Diameter of the pressure needle ball: 0.395 ± 0.005mm, measuring hole diameter of the foot: 1.0 ± 0.15mm, pressure foot diameter: 3.35 ± 0.15mm

4. Compression force: 235 ± 30mN

5. The small thickness of the test piece is 1mm (test pieces smaller than 1mm can be stacked in two layers); O-ring small section diameter 0.8mm

6. Test (pressing) time: 30s

7. Longitudinal large stroke: 30mm

8、 横向大行程： 120mm

9. Lndenter rubber micro type with a diameter of 0.4
