The New Dimension to Resolution: Can it be Resolved? Our last blog, Device Resolution and the Impact on Consumer Risk, described why best practices should be followed for conformity assessments rather than drafting individual test protocols and standards. How should manufacturers and calibration laboratories correctly calculate both uncertainty and risk on equipment? Risk, Conformity Assessment, […]
Morehouse Universal Scale Calibrator The Morehouse Universal Scale Calibrator was designed to accommodate large, high-capacity scales used to weigh aircraft and heavy vehicles. As with any other calibration machine, it is as accurate as the reference standard (load cell or proving ring) with which it is used. Morehouse Universal Scale Calibrators are designed to speed […]
Force Calibration Adapters Guidance: Force-measuring instruments are susceptible to errors from improper adapters, misalignment, and not exercising the instrument to full capacity. Force Calibration Adapters Guidance guides replicating how the force-measuring instrument is used, keeping the line of force-free from eccentric error, and overcoming safety concerns with old adapters. Several force measurement errors can result […]
Device Resolution and the Impact on Consumer Risk - Intro If a device's uncertainty has too coarse of a resolution, then you need a device that does not subject the conformance decision to higher risk. This blog will present examples that demonstrate why best practices should be followed for conformity assessments rather than drafting individual […]
The Standard Morehouse Proving Ring The calibration standard against which all others are measured is available in digital versions. Digital versions have proven to be more accurate, easier to use, and are the preferred option. Proving rings are often the choice for those wanting stability. This page is kept up for reference only. Morehouse Proving […]
Guidance on Uncertainty Budgets for Force Measuring Devices - A2LA: This provides guidelines for identifying all significant contributions to measurement uncertainty in the calibration of force-measuring instruments. It serves as a means for laboratories to be compliant with A2LA R205 – Specific Requirements: Calibration Laboratory Accreditation Program. If you enjoyed this content, check out our […]
TAR versus TUR: Why TAR should RIP ASAP In our last blog, Examining the History of TAR and TUR, we examined several outdated, and to some extent wrong, practices, such as Test Accuracy Ratios (TARs) and requesting NIST traceable calibrations. Remember when they buried the word "DEF"? Maybe we, as metrologists, need to do that […]
Digital Proving Ring Reduces Error The Morehouse digital proving ring reduces operator error and maintains the known stability of a Morehouse analog proving ring. These rings measure the deflection of the ring in digital "counts" rather than by a mechanical micrometer. Calculations can be faster, with less operator action. Proving Rings are known for: Stability: […]
The Design, Development, and Commissioning of a 2kNm Torque Standard Machine for Highly Accurate Torque Calibrations: This is a 2007 article detailing the world's second-most accurate torque machine at Morehouse. Here at Morehouse, we provide torque calibration from 1Nm to 2kNm. For more details on our torque calibration service, click here. If you enjoyed this […]
