H&D 3000

ISO 2781 ASTM D1817

2 instruments in 1: With the MonTech H&D 3000, hardness AND density testing of cured rubber samples is made simple, fast and reliable. Arbitrary test sequences are easily pre-programmed, samples are sequentially processed and test data is automatically collected, without the need for operator involvement. Due to the unique rotary tray design, no manual magazine handling is needed; the instrument can be continuously loaded and operated.

    The H&D 3000 combines two important tests in a single instrument: Hardness and density are simultaneously measured on cured rubber discs. The instrument is completely software programmable for fully automated and unattended sample processing from a 20- position sequential rotary tray. Up to 5 individual Shore A hardness readings can be taken on each sample – afterwards the weight of the sample in air as well as in a temperature compensated immersion liquid is taken. Finally the reliable measured hardness and specific gravity test results, median and mean values as well as Pass/Fail status are automatically calculated and reported.

    Hardness measuring head

    The motorized and weight loaded hardness measuring unit featuring an integrated alignment and a digital measurement of the indentor displacement guarantees the highest precision hardness readings on up to 5 different test points per sample. Various types of hardness heads in accordance to different international standards such as Shore A, Shore D and IRHD are available. (multiple or interchangeable confi gurations available)

    Precise sample handling

    Stainless steel linear, rotational and multiposition electronic / pneumatic actuators provide safe and reliable handling of test samples. Actuators are mechanically separated into two groups: one for dry and one for wet samples to avoid any cross-contamination of the samples prior to weighing in the immersion liquid.

    Integrated pump circuits

    Ensure that the level of the density liquid in the dip tank is carefully controlled. After each density test, an adjustable amount of liquid is automatically renewed, keeping the density liquid fresh and in good condition. Also the pumps can be used to automatically fill, empty and change the density liquid in less than 20 seconds.

    Endless rotary tray magazine

    The rotary sample tray allows continuous operation of the machine, totally avoiding any
    unproductive time. The testing area is separated by a supervised transparent safety door and covers all around the machine.

    Hydrostatic weighing

    Density / Specific gravity is determined by using the “weight in air” and “weight in water” methods. The H&D 3000 features two integrated weighing stations. After weighing the sample in air on the first weighing station, and placing the sample on the second weighing station, a user-defined number of wetting cycles can be programmed to remove any air bubbles around the sample. Afterwards the weight is taken. Simultaneously, the temperature of the density liquid is measured and used as a correction for density calculation.

    All readings are rapidly taken by a precise weighing system based on a standard analytical precision scale, minimizing the possibility of water absorption by the sample.

    Sample removal

    All test samples are automatically removed after being tested and put into a separate container on the lower left side of the instrument. This ensures that rotary tray for fresh samples never gets contaminated with the liquid used for density testing. This ensures the highest accuracy and precision. Optionally, samples can be separated into 2 containers for passed and failed specimens.
