AFFRI Universal Hardness Tester VRS SERIES

Details


ONE BUTTON FOR MEASUREMENT Just press one button and the hardness tester's head moves down to make contact with the sample's surface, clamps the piece, applies the force, makes the indentation and goes back upwards. Within seconds results appear. For Vickers and Knoop indentations, just place the camera in reading position and the indent is automatically measured.		CLOSED LOOP TECHNOLOGY (PAT. AFFRI) When testing unstable samples or deflective parts, the AFFRI System will follow the sample without loosing contact thank's to its 50 mm stroke for indenter and clamping hood. Easy and fast hardness measurements on pieces with different thicknesses without acting on tester head or elevating screw.

MOTORIZED STROKE When testing unstable samples or deflective parts, the AFFRI System will follow the sample without loosing contact thank's to its 50 mm stroke for indenter and clamping hood. Easy and fast hardness measurements on pieces with different thicknesses without acting on tester head or elevating screw.		CLAMPING SYSTEM (PAT. AFFRI) Secure contact with the specimen is always mantained, 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, even if it's oiled, rusty or dirty.

X/Y TABLE Manual XY table 100x100 mm with 10 μm step. This table is a perfect solution for multi indentation test cycles. The table allows manual CHD case depth tests and can be provided with digital micrometers for automatic CHD graph generation.		WORKING BASE 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 pieceholder anvils: from large plane tables to V shaped anvils or special solutions for irregular specimens.

REPEATABILITY & REPRODUCIBILITY 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.		DIGITAL DISPLAY & SOFTWARE Main LCD control panel in front of the measuring head for setting up the test parameters, including powerful software. Fast and easy scales selection and test settings. Results and live statistics. Storage of data and test sessions.
