Chapter 1. Introduction

1.1 Main features and application

TIME TH210 Shore D hardness tester (hereafter called hardness tester) is a kind of advanced integral digital

hardness tester. It includes measuring device and data processing system. It is of the merit of advanced

technology, pocketsize, accurate measuring data, appearance beautiful, light weight, and easy to operate. It

can be connected with computer by RS-232 communication cable. It is mainly used to measure hardness of

hard plastic and rubber such as heat plasticity, hard resin, floor materials, bowling etc. Especially suitable for

finished products in working situation.

1.2 Fundamental

When the steel indenter of certain shape is pushed into the sample surface vertically with testing force, and

when surfaces of pressure foot and the sample touched completely (see figure 1), the indenter extends out for a

certain length "L" from the pressure foot plane. Greater length "L" means lower Shore hardness value and

smaller length "L" means bigger Shore hardness value. The formula is HD=100-L/0.025, HD is Shore D

hardness value in the formula.

The formula indicates that the hardness value is relevant to displacement of

indenter. Displacement of the indenter is measured by the sensor, then the value is given through calculation

and processing of the CPU.
