Fitted with a Digital hour timer, the samples after being digested for 2 hours can be analysed using calorimeter or conventional titration method. To work on 220/230 volts.

Substantial saving of time and advantage of cheapness through saving of power & Costly Chemicals. The determination of carbon and sulphur contents in iron and steel has become an absolute necessity for all iron processing plants foundries etc. There is substantial saving of time, as in a short time, both carbon and sulphur can be determined in one action. The dual determined in one action. The dual determination in excellently suitable for Routine analysis.
