By Mahesh Chander Gupta Like other instruments, engineering-grade ruled scales require traceable calibration. Because the calibration is usually carried out by sophisticated comparators that are expensive to buy and maintain, only a handful of laboratories […]
The NIST fiber probe is a Coordinate Measuring Machine (CMM) probing system intended for diameter and form measurement of micro features and small holes. The Moore M48 CMM at NIST can measure holes down to […]
Whether your quality practices are guided by the need for compliance with the FDA, ISO 9001 or ISO/IEC 17025, a calibration management software solution can be an important central element of your integrated quality system.
National Institute of Standards (NIS), Egypt. The system consists mainly of a fabricated thermal current converter (TCC) associated with a definite hardware and a flexible software. The new system has been harmonized to cover a […]
Metrology impacts the entire product life cycle (PLC). From R&D to product shipment, metrology systems and their data are used to: establish product specifications, determine if the results of a specific measurement conform to stated […]
An ordinary decade resistance is made of ten resistive elements for obtaining ten resistance values with a constant step. A resistance box is composed of more than one decade. In this paper, a new design […]
Gas flow rate measurement devices are usually calibrated in secondary flow laboratories and the lower level measurement standards are conducted to the traceability chain by the primary or national measurement standards which are established and […]
By Roman Honig We can observe an increased interest in high resistance measurements in the range of MΩ to TΩ. This may be related to recent inter-laboratory comparisons in this area, or to increasing activities […]
