  • The "Lixer" provides a NIST traceable standard to calibrate or verify the accuracy of tape measures. It is used to check both the push and pull measurements of the tape measure.  A NIST Traceable Certificate is included with each tool and tape measure.
  • Lixer Tape Measure Calibration Tools have calibration marks for both standard and metric at 10 cm and 6 inches, with the exception of the standard only and metric only gage blocks. The Lixer Square has inspection marks at 3" and 10cm.

    The Lixer A-Class is an aluminum version of the Lixer Tape Measure Calibration Tool.  It has edges milled in the scale bed which provide the reference point for the 10 cm or 6 inch marks of the tape measure. The NIST Certificate for the Lixer A-Class indicates +/- errors within .0005 inches.

  • The Lixer Master is a 303 Stainless Steel version of the Lixer A-Class and is available with Independent ISO Certification.
  • The Lixer Gage Block is a stainless steel version of the Lixer Tape Measure Calibration Tool.  It has the same features for tape measures calibration as the A-Class and Lixer Master, but with additional provisions for verifying accuracy of calipers and identifying Abbe' error, and verifying micrometers. The Lixer Gage Block NIST Certificate indicates +/- errors within .0005 inches for tape measures and actual numbers (ROV) for caliper and micrometer verification surfaces.  Available with Independent ISO Certification.

    A Lixer is . . .

    A Lixer is the only tool designed to check the accuracy of new and used tape measures and straighten bent end hooks. It will check the accuracy of both the push and the pull functions of the tape measure. It will work with most tape measures, both English or Metric. Some tape measures have lost accuracy due to bent end hooks, commonly caused by accidentally being dropped. The end slot of the Lixer is designed to straighten these damaged end hooks.

    The Lixer tape measure is an important tool for all trades that require accuracy in measuring with a tape measure. This is especially important if several tape measures are being used by different craftsmen or at different locations. This will also benefit subcontractors collaborating on the same project. All the tape measures in such an operation need to measure the same. This would certainly be the objective of ISO certification.

    Likewise, we found that by calibrating all the tape measures and equipment to one source (NIST), we could keep the shop running more accurately, and help avoid costly measuring errors.

    In the process of running our custom cabinet business, we discovered that even new tape measures are not always accurate. Sometimes this is due to a burr left on the inside of the tape measure hook during the manufacturing process. We have also noticed a slightly random placement of the end hook. Some manufactures tend to place the end hook more accurately. For these reasons we suggest using a Lixer when purchasing a tape measure, and would suggest a quality manufacturer as well.  (The Natural Finish Custom Woodwork)

    Using a Lixer for ISO applications. . .

    ISO 9001:2008 7.6 Control of Monitoring and Measuring Equipment has been replaced by ISO 9001:2015 Measurement Traceability

    Where necessary to ensure valid results, measuring equipment shall:

    1. a. be calibrated or verified, or both, at specified intervals, or prior to use, against measurement standards traceable to international or national measurement standards; where no such standards exist, the basis used for calibration or verification shall be recorded
    2. b. be adjusted or re-adjusted as necessary;
    3. c. have identification in order to determine its calibration status;
    4. d. must be safeguarded from adjustments, damage, or deterioration that would invalidate calibration status and subsequent measurement results

    Additional information can be found at

    A Lixer will help meet these ISO requirements by:

    1. a. The Lixer with NIST certification gives you traceability to national standards to verify the accuracy of both the push and pull measurements of your tape measure.
    2. b. The Lixer allows you to calibrate the accuracy of the tape measure by adjusting the end hook.
    3. c. When a Lixer is purchased, it comes with a Certificate of NIST Traceability, and has a unique serial number by which to identify it. We maintain a record of the certificates that have been issued.  Annual recertification is recommended for ISO compliance.  A Sticker is applied to each tool indicating the certification date.  We also include a tape measure calibration log with each order.
    4.  d. Tape Measure Calibration Tools come in a padded storage box.

    Protool Reviews

    "Using the Lixer was very simple and we verified that our Starrett tape was accurate on only one side of the tape's end hook. Realizing this, we began checking all our other tapes and had some pretty big revelations as to why some of our cuts recently had left us more than a little long. Once you begin checking your tapes with the Lixer, it's difficult to stop until you run out of tapes. It's fun to use, and so simple you'll wonder why you hadn't done it earlier."

    Here at Knapheide Manufacturing we use the Lixer tool for calibration of our tape measures. The quick simple procedure takes seconds and assures we are covered for ISO certification standards. The tool is a quality piece and performs flawlessly time after time.
