National Physical Laboratory UK


National Physical Laboratory, world's leader in measurement and material science, bought M632 and M602A resistance decades for two of their projects.

Even though the exact application for M632 Precision Real-Resistance Decade in NPL is unknown, it most surely requires highest accuracy (30 ppm) combined with high switching speed (6 ms) that only M632 can deliver. Temperature stability of 1 ppm/°C and smart switching circuit with no residual resistance make the M632 a cutting-edge metrology equipment.
