Estimating measurement uncertainty is one of the most challenging tasks that scientists and calibration technicians have to deal with. When an instrument is calibrated the measurements should be traceable back to a common standard.
All measuring devices loose accuracy over time. Therefore, reliable readings require a regular schedule of calibrations. The particular conditions and needs of each application will determine when it is time to recalibrate a measuring instrument.
This white paper discusses the basics of uncertainty in measurement and calibration. It is not made for mathematicians or metrology experts, but rather for those of you who are planning and making practical measurements and calibrations in industrial applications.
Paper is part of our everyday lives – whether in the workplace or at home. Take a minute to look around the room you are in and you’ll notice how many objects are made from paper: books, magazines, printer paper, perhaps even a poster on the wall.
In applications such as calibrating sensors atop a fermenter tank or smoke stack, using the cloud-based JofraCloud calibration software from Ametek STC, all set points and readings in between can be done remotely.
Ametek Sensor, Test & Calibration (STC) has launched its new Jofra CTC-1205 compact temperature calibrator. The calibrator offers improved calibration times over the predecessor CTC-1200 calibrator and is suitable for waste incineration, power plants, oil and gas production.
