  • Why calibrate PULSE?

    This famous remark emphasises the importance of measurement in the world of science, industry and commerce. We all use and depend on it daily, in even the most mundane aspects of life – from setting your wristwatch to the radio time signal, to filling the car fuel-tank, or checking the weather forecast. All of these things depend on proper calibration and traceability to national and ...

  • Automatic calibration saves big

    Automatic gas sensor calibration technology was developed by Rel-Tek and proven over a decade of industrial applications involving large alternative fuel, transit bus garages.  CNG, LNG, LPG and hydrogen fuels present the possibility of explosive gas buildup indoors, so sustaining the accuracy of the installed gas monitoring system is a never-ending responsibility for the owner.  ...

  • Free-field calibration in China

    Practically all reference microphone calibrations that are performed by national metrology institutes are pressure response calibrations. This is the case even if most practical measurements are carried out under free- or diffuse-field conditions. Fortunately, for measurement microphones, there are essentially fixed ratios between the pressure-, free- and diffuse-field responses. Therefore, the ...

  • Overview of Rotating Disc Electrode (RDE) Optical Emission Spectroscopy for In-Service Oil Analysis

    Introduction The basis of modern oil analysis is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants and additives in oil samples. Whatever else an oil lab may measure, a multi-elemental analysis is the core of in-service oil analysis. This paper gives an overview of Rotating Disc Electrode Elemental Spectroscopy and its ...
