XHA (IRHD) - M semi-automatic miniature international rubber hardness tester

1overview

This instrument is used to measure the conventional hardness of rubber and similar rubber material test pieces and specimens. It's executionGB/T6031-MThe Hardness of Vulcanized Rubber（30-85IRHD）The determination——The standard device for micro testing.

The 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.

pass throughhigh-precisionThe precise coordination between the transmission system and the sensing system automatically completes a single test under the control of the systemIn addition to measuring the hardness of standard rubber test pieces, it can also measure the apparent hardness of small volume finished parts, especially suitable forOMeasurement of apparent hardness of the ring and non-destructive determination of the apparent hardness of the small remaining parts of a damaged component.

The value calibrated by this hardness tester is the international rubber hardness, with a calibration range28-100Degree, this is a conventional hardness measuring instrument, so in the low hardness zone（35High hardness zone below (degree)（85The hardness measurement on surfaces with a hardness of (degree above) and on curved surfaces is approximate and can be used for sampling and comparison of the same type of rubber parts.
