E.S.C.R. Apparatus is used for determination of susceptibility of ethylene plastics to environmental stress cracking when subjected to certain conditions. Bent specimens of the plastics each having a controlled imperfection on the surface are exposed to the action of a surface active agent, oils or detergent. The proportion of the total number of specimens that crack in a given time is observed.
Inside bath is of S. S. and outside bath in M. S. with heat insulation.
The heating system is having a RTD, Heater and Digital Temp. Controller (PID)
Max. Temperature 1500 °C
Max. Temperature - R.T.,
Resolution 0.10 °C
