Lower Your Force Measurement Risk

Measurement risk is the probability that a bad decision will result from a measurement whose consequences can include massive recalls, product failures, significant financial loss, and even loss of life. Accurate measurement data can reduce this risk so you should expect more from your measurements.

Calibration labs are not created equal with significant differences of CMC uncertainty parameters that can range from 0.1 % of applied force to 0.002 % of applied force, like Morehouse; using a force calibration laboratory whose capabilities cannot meet your requirements is like using a ruler to calibrate a gauge block.

Grow Confidence in Your Results

Confidence in your force measurements begins with the force calibration service. Morehouse works with every customer to ensure their instruments are calibrated in the same manner they are being used, which allows our customers to replicate the calibration results in their tests. Not doing so can cause significant errors, meaning 10-50 times that of what is expected.

Our ISO/IEC 17025 accredited measurements are more accurate than any other commercial laboratory, which translates into lower uncertainties for you. Low uncertainties result in broader acceptance limits (using method 5 of ANSI/NCSLI Z540.3 Handbook and allow us to make more statements of conformity “Pass” per the requirements of section of ISO/IEC 17025:2017) and increased confidence in your results.

Obtain Truly Traceable Calibrations

Many standards require calibration, or verification, of measuring instruments with proof of traceability and uncertainty of their measurements. The uncertainty pyramid (left) shows uncertainties increasing with each calibration step or level. From the International Vocabulary of Metrology (VIM 2.41) published by the international authority BIPM, "Metrological Traceability - property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations, each contributing to the measurement uncertainty.

This means that without careful consideration of calibration uncertainty, a proper chain of traceability cannot be established and without measurement traceability, your measurements are invalid. Morehouse is a primary standards laboratory, directly traceable to SI through NIST, helping you minimize your force measurement risk and boost your confidence in your results with truly traceable calibrations.
