Product Description

Feature & Advantage :

  • The IRHD micro compact hardness tester consists of a test stand with an inbuilt support table for adjusting the height of the specimen and an IRHD micro measurement device (ISO 48) with integrated electronics. The hardness tester can be used for tests on O rings, seals, shaped parts and hoses where by the minimum thickness must be 0.6 mm.
  •  A 1 line LC display provides information of the measurement range, the measurement time, and the test data.
  • A code switch allows to set the measurement time (0…99 s) and the language (g/e/f).
  •  The test data is shown automatically on the display after the measurement time has expired. The test data can be transmitted to a PC for further processing and archiving via an RS-232 interface. When using the test software testXpert II the test results are automatically transmitted and statistically evaluated in a correspondingly prepared test report. A meaningful test report is a must according to ISO 9000 to guarantee the best quality of your products.
  •  Convincing points are:
     short familiarization time
     short test cycle
     no tiring approach to the starting test point „100“
     efficient positioning for series tests
     no adjustment necessary
  •  Quick centering device for O rings (option): This test stand is a centering station for Orings to control the positioning as measurements on O rings with an IRHD or Shore hardness tester are almost impossible without a fixing device.
  •  A special centering station for centering rubber hoses is optionally available.
  •  Magnifying glass with swivel arm (option).
