Digital Bench Hardness Tester TH300/301/310/320 for Rockwell Hardness and Rockwell Superficial Hardness Testing

Product catalog summary

Overview: The document provides technical specifications and features of the Rockwell Hardness Testers models TH300, TH301, TH310, and TH320. These testers are designed for measuring hardness on surfaces that are difficult to reach, including internal surfaces of ring parts and external surfaces of round bars.

Specifications:

Design: Horizontal protrudent nose design for testing hard-to-reach surfaces.
Testing Capabilities: Internal surfaces of rings with a minimum diameter of 23mm and external surfaces of round bars with a minimum diameter of 3mm.
Display: High-definition backlight LCD with a simple, easy-to-use operation menu.
Data Output: RS-232/USB data output for easy data transfer.

Models and Features:

TH300 and TH301: Support Rockwell scales A, B, C, D, E, F, G, H, K, L, M, P, R, S, V. They have a resolution of 0.1 Rockwell unit, pre-load of 98.07N/10kgf, and total load options of 588.4N/60kgf, 980.7N/100kgf, and 1471N/150kgf. They feature automatic test processes, data statistics, scales conversion, and curvature correction.
TH310 and TH320: Support Rockwell superficial scales 15/30/45N, T, W, X, Y, and standard Rockwell scales. They have similar features to TH300/301 but with additional load options and slightly different dimensions and weights.

Optional Accessories: Include various anvils, diamond indenters, and mini-printer TA220s for enhanced testing capabilities.

Standards and Compliance: All models comply with ISO6508.2 and ASTM E-18 standards, ensuring reliable and standardized hardness testing.

Power and Dimensions: All models operate on 220v/110v, 50Hz, 4A power supply. Dimensions and weights vary slightly between models, with TH320 being the heaviest at 120kg.
