Indentation Testing Machine

Clear

A high quality machine for the indentation test with advanced auto data logging software to record and present the results via real time charts

The Indentation Testing Machine CRT-IND for determining the resistance to penetration of road and mastic asphalt by loading a cylindrical pin and measuring the indentation in a sample over a given time. The CRT-IND comprises of a frame incorporating a stainless steel water bath with drain facility, method of applying the 500 Newton load and means of recording the test results.* Immersion heater is not included but can be offered as additional equipment. The apparatus conforms to the requirements of EN 12697-20.The maximum nominal size of the aggregates should be less or equal to 16 mm. It comes with optional auto data logging software which saves test data files, shows a graphical representation of the test in real time, reduces operator involvement and thus eliminates chances of error.

Standards

  • EN 12697-20

Key Features

  • Auto data logging software available which:
    – Reduces operator involvement
    – Eliminates chances of error
    – Generates graphical representation of the test in real time
    – Saves operator data, sample information data, time, and pertinent information relevant to the specific sample on test
    – Reduces test costs significantly

    • Heater element to comply with both temperatures requested by EN standard
    • Stainless steel
    • Temperature controlled water bath with drain facility
    • Digital indicator with digital communications.
    • CE Marked and Made in United Kingdom


    Key Use

    • Determines the depth of indentation.
    • To test the behavior of mastic asphalt, rolled and other such asphalts.


    Software

    • CRT-INSOFT, A Cooper Technology designed and developed software package that allows for the automatic capture to PC of test data from the indentation test at the two required test temperatures* and over the four time durations. This software shows a graphical representation of the test in real time, storing the data in text files that can subsequently be opened in Excel.

    *Additional function allows the user to input a temperature between 5°C (or ambient if higher) and 95°C.

  • Accessories

    Accessories are not included in the price of main device (unless stated otherwise) and may be purchased separately if required.
