ASI Dolphin Nose Indenter Digital Touch Screen Twin Rockwell Hardness Tester, ASI-RSR-150NT

Product Overview

The ASI-RSR-150NT is a versatile digital Rockwell hardness tester featuring a dolphin nose indenter for accessing hard-to-reach areas. With touch screen control and closed-loop load cell technology, it supports both standard and superficial Rockwell scales, offering precise hardness measurements without dead weights.

Key Features

·         Dolphin Nose Indenter: Enables testing in awkward locations like ring shapes, tubular materials, screw corners, and bearing edges, ideal for inner surfaces of cardan shafts, bearings, screws, and gearboxes.

·         Touch Screen Interface: Intuitive LCD touch screen for direct selection of test forces and scales, with hardness conversion to HV, HK, HBW, and more.

·         Automatic Load Cell System: Closed-loop structure for easy installation; test forces from 15–150 kgf with <0.5% error and 0.1 HR accuracy.

·         Data Management: USB port for saving test data directly to flash disk in Excel format; dwell time adjustable from 0–99 seconds.

·         Standards Compliance: Meets BSEN 6508, ISO 6508, ASTM E18, GB/T230 for reliable results.

·         Generous Test Space: Max specimen height 300 mm, throat depth 250 mm for accommodating larger samples.

Applications

Suitable for quality control in machinery manufacturing, metallurgy, and laboratories; ideal for testing ferrous/nonferrous metals, hardened/tempered/annealed steel, carbide, powder metallurgy, and thermal spray coatings in industrial and research settings.
