Description

The Universal Hardness Testers LD250 and LD750 offer a comprehensive range of hardness testing methods, including Rockwell, Superficial Rockwell, Brinell, Brinell HBT, and Vickers, conforming to ASTM and DIN EN ISO international standards.

Test Loads:

LD250: 1 to 250 kgf (9,807 to 2452 N)

LD750: 3 to 3000 kgf (29.4 to 29421 N)

Features:

One Touch Measurements: Equipped with the AFFRI System, ensuring high load accuracy and measurement resolution for hardness tests.
User-Friendly Operation: The hardness test cycle is automatically executed with a single start input, including contact with the specimen, active sliding clamping, preloading and loading, switching to optic lens, autofocus by image brightness scanning, measurement through the camera, and return stroke at the programmed distance.
Auto-Contact and Clamping: Fully motorized adjustable testing vertical capacity with automatic contact and clamping from any distance, recognized at any position within the vertical stroke.
Robust Design: Suitable for heavy and bulky samples, easily placed using a forklift or overhead-traveling crane. Capable of functioning in hostile environments.
Auto-Compensation of Deflections: AFFRI System ensures continuous contact with unstable or deflecting samples, maintaining accuracy even in extreme conditions.
Hardness Software: Preinstalled software prevents setting errors, providing color highlighted results, live statistics, test settings programs, result archives, and various export options (PDF, TXT, CSV, DOD, XLS). Supports data entry via code bar scanning and outputs via RS232, USB, and Ethernet. Compatible with INDUSTRY 4.0 standards.
Automation: Fully automated system with features such as auto focusing, automatic measuring and reporting, enabling uninterrupted operation for hours, improving productivity and saving time and money.

Main Components:

Motorized Turret: Automatic two-position turret with one indenter and one objective, allowing for a completely automatic hardness test cycle.
Clamping System: Ensures secure contact with the specimen, maintaining stability throughout the test cycle, even with oiled, rusty, or dirty samples.
Hard Base: Wide work table base capable of bearing masses over 3000 kg and accommodating bulky and irregular test pieces.
Auto Focus: Automatic focus adjustment for precise positioning at any magnification, ensuring high reading standards and reducing reading time.
Auto-Reading Through Camera: Measures indents on various sample surfaces, adjusting light and contrast for accurate readings.
Protected Diamond Indenter: Special protective cup minimizes the risk of accidental shock, ensuring a longer lifespan for the indenters.

The Universal Hardness Testers LD250 and LD750 are designed to deliver accurate and reliable hardness measurements, making them ideal for diverse industrial applications.

MAIN FEATURES

MOTORIZED TURRET

Automatic two position turret with one indenter and one objective, easily changeable with manual screwing. Auto-rotating, auto-tool-switching and auto-centering for a completely automatic hardness test cycle. (On request 8 position)

CLAMPING SYSTEM

Secure contact with the specimen is always maintained, even in the unlikely event of any specimen movement during the operation cycle. The clamping system assures complete stability of any test piece throughout the test cycle, even if it’s oiled, rusty or dirty.

HARD BASE

The wide work table base is capable of bearing masses over 3000 kg and special fixtures or anvils. Hardness measurements on bulky and irregular test pieces which cannot be easily reached by the regular bench hardness testers

AUTOFOCUS

Automatic focus adjustment for each optic with precise positioning at any magnification by mean of real image scanning brightness, at continuous step for infinite accuracy. This system assures high reading standards, reproducible focusing quotes and reduces reading time. Hardness results are not affected by subjectivity.

AUTO-READING THROUGH CAMERA

From perfectly polished to rough & etched samples, the software automatically measure indents on any sample surface. Automatic light regulation on dark, opaque or polished samples. The software controls and adjusts the light and contrast to find the right combination and measure the indent.

PROTECTED DIAMOND INDENTER

All Affri diamond indenters have a life-span longer tanks to the special protective cup. This indenter retracts and moves down just after the test piece is clamped thereby minimizing the risk to accidental shock.
