HL-300A Leeb Hardness Testers use Leeb dynamic method and are used to measure the hardness in metals including steel, cast steel, alloy tool steel, stainless steel, grey cast iron, spheroid iron, cast aluminum, brass, bronze and wrought copper. All of our impact devices (D, DC, D+15, DL, C, G, E) can easily be changed with no need to calibrate the unit.

Highlighted Features

• High Accuracy (0.5%) and Repeatability (4 LD units), operated by normal AA batteries

• Wide Measuring Range with LD hardness value convertible to Brinell, Rockwell, Vicker and Shore scales;

• Menu operation with Large LCD screen (for singer or comparison display of hardness values);

• Automatic detection and application of impact devices (including D, DC, D+15, DL, C, G, E);

• Data acquisition and output by micro-printer with 960 data store capacity;

• Data transferable to PC via RS232 or USB interface and Foresight® software;

• Mean value, max value, min value and standard deviation;

• Reference setting (date, work-piece No. etc.);

• Selection of limitation with a sound alarm;

• Conversion table revision;

• Measuring directions selection - even up-side down;

• Measuring calibration;

• Automatic calibration with standard block;
