Digital Micro Shore Durometer HPE Type M/AM
Digital Micro Shore Durometer HPE Type M/AM

HPE Type M/AM Digital Micro Shore Durometer – Ideal for Thin Walled O-Rings and irregular/thin flat material

ASTM D2240 (type M), ISO 7619 (type AM)

The HPE Type M/AM Digital Micro Shore Durometer is ideal for accurate, repeatable hardness readings on soft elastomers too thin or too irregular in shape for standard Durometers. The HPE Type M/AM Durometer accurately measures specimens down to 1.25 mm. The unique design minimizes material deformation. Test method conforms to ASTM D 2240-00 (Type M) and ISO 7619 (Type AM).

Qualitest’s line of digital durometers revolutionizes durometer hardness testing by utilizing state-of-the-art technology. A highly accurate force and displacement measuring system assures consistent results with accuracy and repeatability. Modular design provides for the ability to change test probes for multi scale testing.
