Rubber Permanent Compression Deflection Tester

This instrument is used for the static energy compression test of rubber. Take the standard test piece, clamp it between the compression plates of this instrument, tighten it with screws, compress it to a certain ratio, and then put it in the oven at a certain temperature (another tick). Take it out after the specified time, remove the test piece, cool it for 30 minutes, test its thickness, and substitute the formula to calculate its compression deflection
