IRHD Hradness tester

The IRHD hardness measurement cycle and the indenter contact with the sample are managed by the software with load control by load cells in Closed Loop (patent AFFRI). This eliminates manual errors and the influences of external vibrations. With a single input, the tester automatically research the specimen, clamps it and shows the result.

IRHD hardness tester eliminates human error increasing the accuracy, repeatability, and reproducibility of the measurements. O-rings can be easily tested using the specific sample holder for each chord dimension of ‘OR’ according to ASTM 1414 without having to perform manual settings. The measurements are stored in the computer hard drive and analyzed for statistical processes.

PRESS A BUTTON, GET RESULTS

Just push the start button and the hardness tester will perform the testing cycle in automatic succession without breaching a phase:

  1. Automatic approach and contact to the sample
  2. Clamping of the sample
  3. Execution of the measurement
  4. Release of the sample

The entire test cycle is complete and the result immediately appears on the large display. Fully motorized and automatic, the test is not affected by operator influences and can easily be used by operators of entry level.

What’s more?

  • 100% made in Italy
  • Robust and resistant in every test condition
  • Hard indenter to guarantee maximum efficiency over the time
  • R&R high performance
  • Clamping system which assures perfect stability of any test piece throughout the test cycle
  • The Affri system (Patent AFFRI) assures exact, precise measurements at the very first test

LOAD CELL AND CLOSED LOOP

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 deadweight 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 TEST RESULT IS CORRECT AND ABSOLUTE, SAVING TIME AND MONEY, THUS INCREASING PRODUCTIVITY

THE SOFTWARE

The IRHD hardness tester is equipped with a 10.4” LCD touchscreen PC support with USB and Ethernet data outputs for full connectivity with network devices, printers, or keyboards. Remote service and assistance through the internet connection. The software controls the whole instrument during the entire cycle avoiding operator errors. This software is user-friendly and easily managed by touchscreen. It is a powerful analysis system with easy and fast test settings, live statistics, and graphs. Large storage of data and test sessions.

TEST DATA IMPORT AND EXPORT

Test cycles can be loaded directly from a central system by means of a bar code scanner. This hardness tester gets all information fully automatically. After test run the bar code data are added with results and immediately returned to the order management system.

MICRO IRHD
HARDNESS TESTER

To perform the test just act on the elevating screw and bring the sample to make contact with the indenter, then pull the START lever and apply the load; within seconds results appear.

  1. Load forces are applied through a dynamometric load cell
  2. It is not affected by vibration and it doesn’t need to be leveled
  3. The Micro IRHD works in any condition due to the Affri System where load forces are directly applied along the indenter’s axis, without ratios and levers
  4. The visible indenter allows reaching extreme points and small details. Different anvils are provided to accommodate any type of sample.

FAST and really EASY bench hardness testers with high accuracy standards
