SPECIFICATION

  • Pentrometer With refrigeration system and micro-processor based digital temperature controller
  • Ductility is defined as distance in cms to which a standard briquette of bitumen can be stretched before the thread breaks
  • The briquette is stretched at a rate of 50 mm/min.± 2.5mm per minute at a temperature of 27°C ± 0.5°C
  • The Machine is having built in refrigeration system to work a below ambient temperature up to 10°C in tropical conditions.
  • The Machine will operate at 27°C with control accuracy of ± 0.5°C as per the requirement of IS
  • The apparatus consists of water bath with a heater, and a circulating pump to maintain uiform water tempetature one half of the briquette moulds is fixed in a fixed plate in the water bath, the other half of the briquette mould is fixed to a carrier which slides over a rotating threaded shaft with a clutch, The motor and gears to rotate the shaft are housed in a cabinet fixed above the other end of the bath.
  • A pointer fixed to the carrier moves over a scale graduated from 0-100 cm x 1mm fixed on the bath with "0" (Zero) of the scale towards the fixed plates side
  • The rotating shaft has 2 speeds of travel for the bracket, 5 cm/min.and 1cm/min selected by a clutch
  • Water bath inside is of stainless steel with insulation and water drain cock
  • A heater with is fitted inside the water bath.
