The PTC® 408 Shore A durometer is used to measure the hardness of softer materials, typically in the Shore A scale. This durometer provides precise hardness readings, which are essential for various applications, including:
Quality Control: Ensuring that materials, such as rubber, elastomers, and soft plastics, meet specified hardness requirements during manufacturing processes.
Material Selection: Assisting engineers and manufacturers in choosing appropriate materials based on their hardness to suit specific applications.
Product Development: Supporting the evaluation of prototypes and formulations to achieve desired hardness characteristics before mass production.
Performance Testing: Helping predict how materials will behave under different conditions, ensuring they perform reliably and safely in their intended applications.
Compliance Verification: Ensuring that products adhere to industry standards and regulations regarding material hardness and performance.
By accurately measuring the hardness of materials, the 408 Shore A durometer plays a crucial role in industries such as automotive, medical devices, consumer products, and manufacturing, contributing to overall product quality and performance.
The Model 408 Type A Durometer is designed to measure ASTM D2240 Type A hardness according to the standard. This includes materials such as rubber, elastomers, and other rubber-like materials, including neoprene, silicone, vinyl, and butyl. Soft plastics, felt, leather, and similar materials generally fall into this same range. PTC®'s Model 408 meets or exceeds current ASTM D2240 Specifications. Accurate readings can be obtained in any position.
The instrument has a low-glare aluminum dial with bold, easy-to-read numbers. The durometer comes standard with a Max Hold hand, which retains the peak reading. The case tapers to a base that is 1” x 1” to allow better access to confined areas. A removable top knob (8-32 threads) permits both easy handheld use and attachment to test stands or a 1 kg deadweight.
These durometers can be used
with either a test stand, a handheld, or the constant load weight model
441.
