Affri Automatic Universal Hardness Tester – LD250 / LD750

ONE TOUCH MEASUREMENTS

Universal Hardness Tester with AFFRI System inside!

AFFRI System hardness testers achieve the highest level of load accuracy and measurement resolution available for hardness tests.
Thanks to the AFFRI System, the real indentation measurement is guaranteed without any external interference in any condition.

What makes our hardness tester so easy to use?

Just push the start button and the head moves down performing the hardness test cycle in automatic succession without breaching a phase:

1. Contact with the specimen
2. Active sliding clamping
3. Preloading and loading
4. Switching to optic lens
5. Autofocus by image brightness scanning
6. Measure through camera
7. Return stroke at programmed distance

The entire test cycle is automatically completed and the result appears on a large display.

SPECIMEN AUTO-CONTACT AND CLAMPING

Fully motorized adjustable testing vertical capacity including automatic contact with test surface and clamping from every distance with single start input. The activation of the test cycle is automatic, it starts when the head makes contact with the specimen which is automatically recognized at any position within the vertical stroke.

Vertical capacity from indenter to the base LD750: 720mm / 28″ LD250: 390mm / 15″

Horizontal capacity from column to the indenter LD750: 265 mm / 10.5” LD250: 190 mm / 7.5”

Our universal hardness tester is a robust, reliable system, designed to function even in hostile environments. Heavy and bulky samples can be easily placed using a forklift or overhead-traveling crane.

AUTO-COMPENSATION OF ALL DEFLECTIONS

When testing unstable samples or deflecting parts, the AFFRI System will follow the sample without losing contact thanks to its stroke for indenter and clamping hood.

Load forces are applied through load cells and controlled in “Closed Loop” with a frequency of 1 khz, assuring perfect linearity in every range. Results are not affected by any structural deflection, misalignment or vibration.

Accurate measurements on the first test, even in extreme conditions, eliminate the need for repeated tests. The R&R data is at the top of its class.

THE NEXT AUTOMATION UPGRADE

EVERYTHING IS AUTOMATED, FREEING USERS FOR OTHER TASKS:

Auto focusing, automatic measuring and reporting, allows this system to function unattended for hours without interruption, saving time and money, thus increasing output and productivity.
