    Q1: What is a Shore hardness tester?
    A1: A Shore hardness tester (Shore durometer) is widely used in the hardness determination of rubber and plastics. It has a simple structure, convenient use, small size and light body, and intuitive reading. Digital Shore A/B/C/ D/DO/E/F/O/OO hardness testers are available on

    Q2: What are the 6 steps of sisco hardness tester measurement?


    1. The specimen should allow the measurement to be taken at least 12 mm from any edge. The specimen surface should be flat and parallel to allow the presser face to contact the specimen over an area that has a minimum radius of 6mm from the durometer probe. The specimen may be constructed with layered pieces to achieve the necessary thickness requirements, however, measurements taken on these specimens may not agree with those made on solid specimens, due to the surface faces between layers not being in complete contact.
    2. Depress and release the “Power key" to power the tester on.
    3. Depress the "MAX" key till the mark MAX shows on the display.
    4. Hold the durometer vertically with the point of the indenter at least 12 mm from any edge. Apply the presser foot to the specimen as rapidly as possible, without shock, keeping the foot parallel to the surface of the specimen. Apply just sufficient force to obtain firm contact between the presser foot and the specimen. Hold for 1 or 2 seconds, the maximum reading can be obtained automatically.
    5. To take the next measurement, just depress the "Zero key" and repeat 4. On the other hand, you can depress the "Max hold key" till the mark MAX disappears from the display. And then repeat steps 3 and 4.
    6. If other than a maximum reading is needed, no need to set the mark "MAX” showing on the display. In such cases, the reading on the display is an instant value. Just hold the durometer in place without motion and obtain the reading after the required time interval ( Normally less than 1 second)

    Tips: How to take the average value of Shore hardness tester?

    1. To take the average value of many times of measurements,  just depress and release the "N/AVE key" to make the symbol "N" showing on the display, followed by a digit between 1-9 with the prefix. Here the digit is the time of measurements used to calculate the average value. Every time depress and release the "N/AVE key", the digit will increase by 1. And the digit will become "1" while depressing the "N/AVE key" at "9".
    2. Adjust the digit to the number needed and depress the "MAX key" or "Zero key" to return to the measurement state or wait for several seconds till"0" on the display.
    3. Take measurements correctly. Be sure that every test should be 6 mm apart. Every time take a measurement, the reading and the times of measurements show on the display. When the times of measurements are equal to the number set, the unit first displays the reading of the last and then displays the average value of the last "N" measurements, followed by 2 beeps, with a symbol "AVE" indicating on the display.
    4. To take the next average value, just repeat 3.
    5. To release from average measurement, just depress the"N/AVE" till "N" disappears.

    Reliable hardness tester
    I recently purchased a Shore DO hardness tester for use in our lab and it has worked great so far. The tester is well-built and feels solid in the hand. It's also very easy to use - you simply press the probe against the surface of the material to be tested and read the result on the digital display.
