Durometers by PTC Instruments

Durometer Spring Load Cell Stand:

PTC®s line of Test Stands have been engineered for rapid, repetitive durometer hardness testing. These stands are easy to use and have been built to last for many years of service. The Test Stands are designed to provide the ASTM recommended forces for use with PTC®s Durometers and are also fully compatible with durometers of other manufacture and several mounting configurations. The ConstaLoader Test Stands are precision engineered with an oil-free airpot to give a smooth, controlled rate of descent as recommended by ASTM D2240. These stands and your durometer will make the most accurate readings with improved repeatability and reproduceability. Ideal for applications with multiple operators or where fatigue may be a factor in repeating durometer hardness measurements. Quality built using aircraft aluminum and hard anodized for a long lasting finish.

Test Stands can be custom engineered for measuring unique items or materials. Contact us with your specifications, we can design a test stand and durometer for your application.

320 SPRING LOAD CELL STAND for Classic & Ergo Style Durometers Type A, B, C, D, DO, E or O.
825.00
The 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 with a threaded top. This precision engineered stand has a calibrated load cell to provide the ASTM recommended forces for Types A,B,C,D,DO, E or O. The table is self aligning to allow testing of materials with nonparallel top and bottom surfaces. Manual operation of a durometer will 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.
