AFFRI LD Brinell Hardness Testers

One Button Automatic Measurements

Press the START button and the measuring head approaches the sample, applies the load to perform the indentation and goes back up; all in automatic succession without breaching a phase. The measuring cycle is a fully motorized electronic system for automatic preloading, loading and measurements. The test cycle is not affected by operator influences and can easily be used by operators of every level.

Load Cell and Closed Loop Technology

Load forces are applied through load cells and electronically controlled in “Closed Loop” with a frequency of 1 kHz. Results are not affected by any structural deflection, misalignment or external vibration. Accurate measurements, even on the first test, eliminate the need for multiple tests. The first test is correct and absolute, saving time and money, increasing output and productivity.

Motorized Vertical Stroke

Fully motorized measuring head with a vertical sliding stroke of 1.2" (30 mm). When testing unstable samples or deflective parts, the measuring head will follow the sample without losing contact, compensating any frame deflection during the test cycle. Accurate results are assured even with oiled, dusty or dirty pieces. 

Clamping System

Secure contact with the specimen is always maintained, even in the unlikely event of any specimen movement during the operation cycle. No additional support accessories are required.

L.I.S.A - Laser Indicator System AFFRI

Exclusive application which allows ultra-precise test positioning. It can reach extreme points with lack of illumination, edges of gear's teeth, or sides of cutting tools and blades.

Protected Indenter

The indenter is protected and retracted, it only moves down after the specimen is fully clamped and stable, minimizing the risk of accidental damages.

The LD 3000 A measuring probe is a light and handy system which can work in any direction. The microscope uses a high definition camera for the automatic reading of the indentation diagonals or diameter. It is equipped with a powerful LED light source and has a long-life span.

Easy to Use

Put the test probe on the surface to find the indentation and push the red button on the side of the handle.

• Magnetic base for safe clamping on any iron sample. Stable positioning when reading the indent with no need to hold the probe with your hand.
• Automatic light and contrast adjustment with live immediate correction on any dark or bright sample surface.

Touchscreen and Software

Features a side touchscreen for easy test planning and a clear view of results. It has user friendly Windows® interface and it can store testing sessions in the large memory library using the on-board software database.
