SST300 inclinometer is excellent tilt device which not only have outstanding performance, but also have simulation & process with advanced EDA&CAE technologies including reliability design, strict process control, structure design, components/materials collection & heat treatment, heat flow analysis, finite element analysis and so on, to achieve high reliability and stability. Each inclinometer performed with Vigors patented automatic testing technologies without manual operations and unpredictable random errors occupied. Not only general accuracy test, but also temperature drift compensation, nonlinear correction, cross-axis sensitivity error correction, and/or orthogonal error correction, input-axis misalignment compensation, vertical-axis misalignment compensation, as well as life test, made to reduce additional error caused by filed installation, then realize to installed-to-forgot and acquire accurate data.
