Rockwell method measures the permanent depth of indentation produced by a force. Press the indenter into the sample surface with the initial test force, and then apply the main test force. After remove the main test force, the depth of the indentation indicates the hardness. TH300/320 rockwell hardness tester is featured with protrudent indenter to test hard-to-reach places and automatic loading/unloading. 

Features

High accuracy, wide measurement range, automatic loading and unloading of major load

Test results display digitally, and can print automatically and connected to PC.

High definition Matrix LCD display with backlight

Optional indenters meet different test requirements: TH300 protruding indenter for ring and groove; TH320 for all kinds.

Conversion of common hardness scales (HLD, HV, HB) & Conversion of Tensile Strength,up to 15 kinds of Rockwell hardness scales.

Collect statistics includes values, mean value, Maximum, Minimum and Standard Deviation

Round correction: cylinder and sphere surface

Upper /lower limits pre-setting and sound alarm

Comply with GB/T230.2, BS EN10109-2, ASTME-18, ISO6508.2 and other applicable standards.

Automatic test process

RS 232/USB data output
