|One Button Measurements|
|Just push the start button and the head moves down performing the hardness test cycle in automatic succession without breaching a phase:
|Motorized Vertical Stroke|
|The MRS measuring head is fully motorized with a vertical sliding stroke of 50 mm/2". When testing unstable samples or deflective parts, the measuring head will follow the sample without losing contact. Easy and fast hardness measurements on pieces with different thicknesses without acting on the tester head or elevating screw.
The top surface referencing design minimizes errors caused by problems associated with dirt or scale. This reduces sample preparation time and increases both accuracy and speed.
|Load Cell and Closed Loop Technology|
|Load forces are applied through load cells and electronically controlled in "Closed Loop" (Pat. AFFRI®) with a frequency of 1 kHz. Each load force is automatically programmed and controlled assuring perfect linearity in every range eliminating the problems associated with traditional dead weight system testers. 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. There is no need to perform a second test, the first one is absolutely precise. The R&R (repeatability and reproducibility) data is at the top of its class.
The first result is correct and absolute, saving time and money, thus increasing output and productivity
|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 perfect stability of any test piece throughout the test cycle, it moves with the head for the whole vertical stroke generating a constant pressure. This feature allows steady measurements on medium-large specimens.|
|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 exclusive AFFRI® diamond indenter has a longer life-span than any other indenter on the market.|
|Vertically sliding chromed work table capable of bearing masses up to 2000 kg which allows for steady hardness measurements on bulky or irregular pieces. It is possible to install different types of piece holder anvils: from large plane tables to V shaped anvils or special solutions for irregular specimens.|
|Laser Indicator System AFFRI® (L.I.S.A) (Patented)|
|Exclusive application which allows ultra-precise test positioning. The laser pointing system helps to define the indentation area before the contact between the indenter and the specimen. Reach extreme points with lack of illumination, edges of gear's teeth or sides of cutting tools and blades. (This application is optional)|
|The 250MRS hardness tester guarantees maximum reliability even in bad conditions. 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.|
|AFFRI® provides a large variety of accessories to fulfil any purpose of test. Customized solution based on client 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.
Large variety of high quality indenters with certificate. Ball, cone, tungsten or diamond indenters for each hardness scale Rockwell, Vickers, Brinell, Knoop and Shore.
Test blocks for the hardness tester periodic calibration with UKAS/ACCREDIA certificate, for any hardness scale and value.
All AFFRI® accessories are customizable according to customers specifications, depending on dimensions and geometry of the samples and finished products.
