LNP Universaltester
The LNP® Universal Tester is a fully automated benchtop system for standardized hardness testing of elastomers, rubber, and plastics using the IRHD-M method. The instrument combines a high-precision measuring head, motorized Z-axis, stable granite base, and dedicated software for test control, evaluation, and documentation of results.
It is particularly suitable for small, thin, or geometrically complex components such as O-rings, seals, diaphragms, and other technical elastomer products where repeatable measurements with minimal operator influence are essential.
