by Hening Huang This paper further explores the t-interval method and the mean-unbiased estimator for uncertainty estimation with a small number of measurements. It describes the logic behind the error bound-based definition of uncertainty, which […]
by Kevin R. Abercrombie Laboratories are often faced with budget constraints that limit the amount measurement system infrastructure upgrades that can be accomplished in any fiscal year. This paper describes a risk based approach to […]
by Martin de Groot This paper discusses the calibration of pipette, with particular attention to the type that is used and calibrated most frequently. This is the so-called air-displacement pipette, single channel, adjustable volume pipet. […]

by Michael Schwartz This paper covers the progress of the MII (Measurement Information Infrastructure) effort to create a standard for expressing a calibration laboratory capabilities, ISO/IEC 17025 Scope of Accreditation (SoA) in a XML formatted […]
by Jerry Eldred Although rise time is a common calibration measurement in pulse/function generators and some oscilloscopes, it is often not well understood. Making a good rise time measurement is somewhat similar to home stereo […]
by Richard Steven & Joshua Kinney Cone DP meters are a member of the generic DP flow meter family. Used extensively throughout different industries for quarter of a century, the cone meter is now a […]
by Sita Schwartz, Editor For an industry outsider looking in, an awful lot of metrology technicians and metrologists have their background in the military. There’s a reason for that: Precision Measurement Equipment Laboratories (PMEL) schools […]
