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.
