Abstract

Improvements in materials testing instruments, and more particularly in instruments that use deionization radiation to test a material in terms of the presence and magnitude of a certain characteristic, capable of detectably modifying ionization radiation used, characterized in that the instrument comprises a radiation source that emits ionization radiation of a type chosen as capable of being detectably modified by a certain characteristic of the material being tested, said radiation source being supported in a geometric relationship predetermined with respect to a test sample of a material under test and a standard sample of a material known to possess the certain characteristic, to simultaneously irradiate the samples with the ionizing radiation emitted by said radiation source, detection means to perceive l The modifications of the ionization radiation emitted by said radiation source introduced by said certain characteristic of the samples, and which include detectors, first and second, supported respectively in a determined geometric relationship with respect to the test sample and the sample normalized for simultaneously and independently perceive radiation as respectively modified by them, and indicating means operatively connected to said detection means and acting in response to their perception of radiation as modified by the samples to indicate the presence and magnitude of said particular characteristic of the sample material being tested, including dividing means for expressing the response of said first detector in a predetermined relationship with the response of said second detector, so that the instrument is calibrated by a correlation of the Relation of the responses of the detectors to the magnitude of the determined characteristic to be determined.
