The IRHD (International Rubber Hardness Degrees) Rubber Hardness Tester has a spherical indentor, which indents the sample under a minor and major load. The differential indentation depth is measured and tabulated to read directly in "IRHD" degrees. The displacement / IRHD degrees conversion table is published in ISO 48: 1994.

Controller

Sizes 4" x 4" x 9"
Rating Approx.: 2.5 KW
Also available model upto 1200°C

Specific gravity of any elastomer is of considerable importance of its identification. Besides it can also be used for finding if the sample and the products are from the same compound or not.
Ranges available: 0.2 -2.0 & 0.9 -3.0

The Ultra Low Temperature Freezers are equipped with special air-cooled compressor and CFC free refrigerators to give the efficient cooling and flow in the cabinet. High capacity air-cooled condensers with aerodynamically shaped fans and washable condense filter keep fine free of dust to maintain utmost cooling efficiency.

Features:

The tester is designed & manufactured in accordance with DIN standard. It is used for uniformly tests and comparison test of rubber Abrasion abrasive paper is wound on the surfaced of a rotary drum and rubber specimen subjected to load is moved on the abrasive paper. Amount of rubber reduced in the specimen due to abrasion is measured. In this method of testing abrasion, test specimen does not always move on the same path on abrasive paper, but gradually a new portion of the abrasive paper appears to rotation of the drum.

The die is made from high quality die steel to give long lasting finish and accuracy. The die is hardened & tampered and is yellow zinc plated for corrosion free usage. The die is supplied in wooden boxes for safe usage. Standard Size supplied: 115 mm Cutting Press to be bought Separately
