  • 1.  Thickness Measurement

    Posted 11-13-2020 10:34 AM
    Hello,

    Does anyone have any recommendations for an instrument or procedure that can measure thin material accurately and precisely. Looking for equipment that can take readings to 0.0001 inch. Current instruments we are familiar with only take readings to 0.001 inch.

    Thanks you in advance.

    What kind of material do you need to measure? is it film?

    Hello
    I know Magna-Mike® 8600 is a portable thickness gage but it depends on the material you intend measuring.

    I used it for thin PET sometimes ago.

    Thanks and hope this helps.

    Regards

    For film, we are using Mitutoyo  Code 543 392B
    Model ID112EXB  with control cable
    0.5" to 0.00005"
    12.7 to 0.001 mm

    installed on  Mitutoyo Stand Code 7007-10 and

    I used an older Magna-Mike before I retired.  Very versatile.  I used it primarily on glass and plastic bottles and jars, but also used it on other materials and package types.

    There are different precise micrometres available that have a LC of 0.002mm. This is an option if you are slightly low on budget. You may also check Olympus devices. https://www.olympus-ims.com/en/38dl-plus/
    These are ultrasonic based transducers for precise thickness measurements.

    Hello Abhijeet,

    Ultrasonic thickness instruments are effective with various metals and polymers.  A good digital micrometer Is from TESA Brown & Sharpe. Some companies will let you evaluate units for a week. 

    Kind regards,

    Ames 55212 and 56212 are hand held paper style micrometers.  I use these in the field.   These are analog devices with jeweled movements  that are graduated in 0.0001 increments, or ten-thousandths of an inch precision.     The accuracy of this, or any measuring device depends upon calibration, or at least the ability of the device adjustment to measure zero.  Depending upon the fineness of your measurements, you may wish to invest in a gauge block that will calibrate your micrometer within the range of measurements that you are taking.   For instance, if you are measuring 4mil films, you would want a 4 mil or 0.004" gauge block.   
    Hand held analog micrometer with 0.0001 precision.

    General procedure:  Clean the tool by closing it gently on a piece of paper or similar material.   Drag the paper through the space between the foot and anvil to remove any residue.  After removing the paper, adjust the face dial so the needle is on 0.   Condition the sample you are testing in a similar way, to remove dirt, dust etc.  Avoid measuring near creases, cuts or wrinkles.    Lift the foot of the micrometer off of the anvil by moving the lever with your right thumb.  Place the sample to be tested in the throat of the micrometer and release the thumb lever.   Take your reading by looking squarely at the dial avoiding parallax.    Repeat this process until you have taken several identical or near identical measurements.   Compare your observed measurements with the values that you expected.   If the values are not close to your expectation repeat the process.  The flatness of your sample will have an affect on the accuracy of your measurement.   If your samples have a lot of curl, you should be sure that the force of the foot on the sample pushes it flat on the anvil.
