XHA (IRHD) - M Miniature International Rubber Hardness Tester

XHA (IRHD) - M Miniature International Rubber Hardness Tester

XHA (IRHD) - M Miniature International Rubber 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 "Determination of Hardness (30-85IRHD) of Vulcanized Rubber - Micro Test".

XHA (IRHD) - M Miniature International Rubber Hardness TesterThe working principle is that under a certain load, the pressure head acts on the measured object, and different indentation depths are obtained due to the different hardness of the measured object. Based on this, the hardness of the measured object is calibrated.

XHA (IRHD) - M Miniature International Rubber Hardness TesterThrough the cooperation 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.

XHA (IRHD) - M Miniature International Rubber Hardness TesterThe calibrated value is the international rubber hardness, with a calibration range of 28-100 degrees. This is a conventional hardness measuring instrument, so the hardness measurement in the low hardness zone (below 35 degrees), high hardness zone (above 85 degrees), and on curved surfaces is approximate. It can be used for sampling and comparison of the same type of rubber parts.
