AFFRI LD Brinell Hardness Testers

AFFRI LD Brinell Hardness Testers

Overview

AFFRI LD Series Hardness Testers come in 3 available models:

  • LD 3000 Manual - Semi-automatic Brinell Hardness Tester. Reading of indentations are made through a standard microscope or through an optional electronic microscope with auto-measure.
  • LD 3000 A Automatic - Automatic Brinell Hardness Tester with on-board LCD and portable probe. Real Brinell HBW in compliance with ASTM E10 and ISO 6506.
  • LD 3000 B Automatic - Automatic Brinell Hardness Tester with depth hardness measurement for Brinell HBWT and Rockwell in compliance with ASTM E18 and ISO 6508. On-board LCD.

Features

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.

Extreme Precision

The synergy between the tester features allows for a correct result even if the piece is badly positioned. The measurement is not compromised if the piece is dirty with oil or dust.

Elevating Working Base

Vertically sliding chromed worktable capable of bearing masses up to 6,600 lbs. (3000 kg) which allows for steady hardness measurements on bulky or irregular pieces.

LD 3000 A

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.

LD 3000 B

Fully Motorized Hardness Tester 

The LD 3000 B hardness tester is a fully motorized system for automatic preloading, loading and measurements. It can perform every hardness scale for universal use in your own laboratory. The LD 3000 B performs direct reading for Rockwell and Brinell HBWT up to 3000kgf and can also be used to generate Vickers and Brinell HBW indentation.

Special Model for Case Depth Measurement

The hardness tester LD 3000 B can determine the case hardness depth (CHD). Testing can be performed on a non-metallographic prepared specimen. The system will determine the superficial hardness and its effective depth (CHD), from 0.05 to 0.071 in. (0.12 to 1.8 mm), without having to destroy and test the specimen.

Accessories

We provide a large variety of accessories to fulfill any requirement. Customized solutions based on your needs can be made for perfect tests on rough pieces. A series of different anvils is available to test every size of test piece. Variety of accessories to facilitate testing on small or oddly shaped items.
