An  insulating powder is  enclosed in a cavity of two concentric spheres. The inner space of the inner sphere contains the mica heater controled by the dimmerstat. The tappings on the surfaces of the inner sphere and outer sphere are used to find out the temperature difference between the spheres.SPECIFICATIONS:1.  Inner sphere ..

Slabs of equal thickness are placed on either sides of heaters and cooling plates through which water is circulated .SPECIFICATIONS:1.  heater plate   a)  110 mm mica heater  between copper plates.  b)  Radial guard heater plate I.D. 120mm and OD 200 mm    mica heater sandwiched between copper pla..

An electrical heater sandwiched between two plates. The heat loss from hot plate is prevented by using two  heaters and heat of removes heat from liquid by circulation of water. SPECIFICATIONS:1.  Guarded hot plate assembly comprising of main heater, ring guard heater and  top guard heater, mounted over the liquid test cavity.Mu..

The apparatus consists of a copper bar, which is heated at one end, a heat sink isprovided  at  other  end.  The  test  section  of  bar  is  properl y  insul ated  and thermocouples are attached along the length of bar. Heat conducted through the section of bar is measured by heat ..

While calibrating, thermocouple is once dipped in ice for 0Q C and  then  in  boiling  water  for  100°C.  This  is  done  till  the thermocouple shows the actual temperature of ice (0° C) and boiling wafer (100°C) and a linear calibration is set. SPECIFICATIONS:1.  A digital mV Me..
