DDM 900 precision indicator - Dostmann

DDM 900 precision indicator - Dostmann

The DDM 900 is designed for precise temperature measurements as demanded in calibration-laboratory use and quality assurance. The accuracy is adapted to the uncertainties of fix-point-cells for precise sensor calibrations. Pt 10-, Pt-25- and Pt 100-Sensors can be used at the same time. The resolution of up to 0,02 mK often is needed in physical and chemical laboratories.
