Giá đồng hồ đo độ cứng cao su, nhựa PTC Model 320
he Model 320 Durometer Stand is an accessory to PTC®'s line of 300 and 400 Series durometers and is also fully compatible with most durometers of other manufacture. This precision-engineered stand has a calibrated load cell to provide the ASTM recommended forces for Types A, B, E, O and C, D, and DO.
PTC's innovative design allows the user to lock the table perpendicular to the durometer or be used in the self-aligning mode to accommodate non-parallel material test specimens.
Manual operation of a durometer may cause variations in the results attained. Improved repeatability may be obtained by using a mass securely affixed to the durometer and centered on the axis of the indenter. Recommended masses are 1Kg for Type A, B, E, and O durometers, 5Kg for Type C, D and DO durometers. The stand will test materials up to 5 inches thick. Custom stands are available for larger samples.
