    Rebound hardness testers     (standardised in DIN 50156 and ASTM)

 working principle  A preloaded spring will throw a probe (body with integrated hard metal ball) with defined speed on the test piece. The measuring system compares the throwing speed and the rebound speed and evaluated on the speed difference the hardness in electronic way in scale HL (hardness Leeb). The result HL or converted results (Rockwell HRC / HRB / Vickers HV / Brinell HB / Shore HS) will be displayed directly on the LCD panel.

minimum weight of the test piece (vibration has to be limited): 2 kg

UCI Härteprüfer Ultrasonic Contact Impedance

 working principle  At the UCI hardness testers on the probe there is applicated a Vickers – test pyramid 136° made from synthetic diamond. The probe will activate to resonance. The indenter will penetrate with defined force (spring loaded) the test piece. Depending on the hardness the penetration depth is different. So the damping of the resonance will be different as deeper (weaker) the material is. The difference between applied resonance and measured damped resonance will show with high precision the hardness value (or converted to other scales). The equipment will be calibrated to YOUR material. The hardness tester is designed as a portable system to evaluate the hardness of materials in the same alloy characteristic. The reliability of the system is limited depending on the E-modulus. If you are not sure that the alloy is in a special range / type of alloy you will receive wrong results. So if you are testing a austenitic steel with a calibration of low alloyed carbon steel you will have an error in hardness as wide as the difference between this two types of alloys is: carbon steel 210.000 MPa / austenitic steel 195.000 MPa) = ca. 7 % mistake of result.
 

   Portable clamping hardness tester    (possible: DKD - calibration)

 working principle  A c-shape clamps the test piece like a mounting clamp. The test load will be applied by spring loading system (maximal ca. 187.5 kg or 3000 kg)
with hand lever (with crank handle and gear box) with high precision. At the smaller equipment (187.5 kp) a depth measuring gauge will show direct after the test the depth of penetration (Rockwell) or HBT / HVT (depth measuring of Brinell + Vickers). For norm conform testing you also are obliged to measure the diagonals of indentation by using a portable optical microscope.

At TBH equipment you may evaluate the hardness by using a portable microscope.

UCI hardness tester IN-HV450 – ready to use equipment:   € 3.395,00
test stand for stationary use if the hardness tester               € 1.595,00

• Portable, easy to use

• High accuracy hardness test

• Digital indication of result

• Direct converting and displaying in different hardness scales

• Option to calibrate the equipment also for values outside standard ranges

The INNOVATEST IN-HV450 hardness testing equipment differs completely from traditional hardness testers. In place of measuring diagonals of the indentation (Vickers / Brinell) with optical measuring system or with depth measuring system (Rockwell) this testing method is using a complete different physical principle.

A synthetic diamond is applicated on to a test probe. This diamond is shaped like a standard Vickers indentor. The probe will set under oscillatory pulsing (approximate ca. 80.000 Hz). The testing force will applied by a spring load when pressing the probe holder on to the test sample. A precision spring will grant that the required test load is applied with high accuracy.

The dumping of the probe (measured dumping of the oscillatory pulsing) will be higher as more the indentor will dive into the test piece. In correspondence to the applied test load the dumping of the resonance will be evaluated as hardness.

The E-modulus of the test specimen will influence the dumping of frequency (the hardness). Testing low alloyed carbon steel or standard alloyed steel this differences are very small. Her you may use standard hardness test blocks for calibration. For different materials (with different E-modulus) you have to calibrate the hardness tester with different references (carbon steel, aluminium, zinc, austenitic steel …)

The hardness test equipment IN-HV450 is easy to use. To perform a test you don't need special knowledge for hardness testing. The result can be converted to the common hardness scales like HV, HB, HR, and Shore. Also after the test you may change the scale by easy pushing one button.

The actual result and scale will be indicated on a big LCD display. To perform a test the hardness tester pencil will be pushed again the test sample for some second. After counting the required penetration time the electronic directly shows the result. A calibration for different materials can be done in quick way. On a hardness test block (where you no the hardness exactly) you will perform 5 "blind" tests. After finishing this 5 tests the equipment asks for the required hardness (from the hardness test block) to be entered into the electronic. Now the equipment is ready for testing.

By storing the calibration you are able to calibrate different testing conditions: From a standard hardness test up to special customised tests like welding or competitive testing. Use the IN-HV450 for incoming goods, material on you stock or as portable tester on testing welding and tubes on gas or oil pipes. The portable equipments works with batteries or optional power supply.

The equipment is comfortable and easy in handling. It is designed for hardness testing at materials from which the hardness are known (referenced – for example carbon steel, austenitic steel, aluminium or other.

In principle this hardness tester is not for "absolute" test suitable because the measurement has to be referenced to a material you have checked on a stationary hardness tester or with reference hardness test plates. When you know the hardness of the material (material class like low alloyed steel, fast working steel, austenitic …) you will make 5 "blind" tests with the CV-HV400. Than the electronic will ask you to insert the desired hardness value. From now on the hardness tester is calibrated (for example with calibration "Method low alloyed carbon steel". Use this method for all steels of this group – even it is weak or hardened…
If you are not sure that the alloy is in a special range / type of alloy you will receive wrong results. So if you are testing a austenitic steel with a calibration of low alloyed carbon steel you will have an error in hardness as wide as the difference between this two types of alloys is: carbon steel 210.000 MPa / austenitic steel 195.000 MPa) = ca. 7 % mistake of result.
