Viscosity Scale, Model 458
The Model 458 Nomogramme dial is used to convert viscosity measurement data for different measuring units at a fixed reference temperature within a measuring unit system. The VISCOSITY NOMOGRAMM can convert viscosity data specified in the following units (reference temperature range 15 ° – 25 °C): cSt = mm²s-¹, cP = mPa s, Engler degrees, Krebs-Stormer units, Gardner-Holdt units, outflow seconds according to ISO 2431 (4 mm)/ASTM D 1200 (Ford No. 3, No. 4)/DIN 53 211. The VISCOSITY TEMPERATURE COMPARATIVE DIAL is used to convert viscosity data for reference temperatures in the range of 5 ° to 30 °C.
