CALIBRATING THE SENSITIVITY OF AN AX1007CP MASS COMPARATOR ACROSS THE ENTIRE ELECTRICAL RANGE USING MICRO MASS STANDARDS

James Berry

Abstract

A new type of mass comparator (AX1007CP), designed for use under a constant pressure has been evaluated. The comparator has a readability of 0.1 µg and an electrical weighing range of 1.5 g. It is installed inside an airtight stainless steel chamber allowing mass comparisons to be performed under fixed environmental conditions. This paper describes the use of micro-mass standards to assess the linearity of the comparator at points evenly distributed across the weighing range.
