ACCESSORIES
Platinum Du Nouy ring
Pt-Ir-ring made to fulfill the requirements at least in following standards; ISO 301, ISO 4311, ISO 6889, ASTM D1331 and ASTM D 971. Includes also additional weight for push-mode.
Thermostatic vessel
Chamber made from Teflon and Aluminum for temperature control of the sample liquid. A heat exchange vessel with fluid jacket type of construction. Heating/cooling of the fluid jacket requires external bath/circulator (T102ME or T102USB). Fits glass sample vessel 70 mm in diameter (T104). Operable temperature range from -20 to +200°C .
RS232-compatible printer
For printing results directly from instrument into paper.
