The J.P.T.I. unit consists of a three slabs of different materials namely mild steel, wood & Bakelite. Nicrome heater is provided to supply heat input across these composite walls. Total heater assembly comprises of a heater bound between two aluminium plates, on both sides of this heater identical structures of composite wall are placed. Thermocouples are provided at proper position in the composite wall to record desired inside temperature of composite wall. Multichannel temperature indicator is used to measure this temperature. Small hand press provided to press the wall on each other & to ensure that no air gap remaining between two plates. Heat input to heater is given through a variance & measured by voltammeter & ammeter. By varying heat input & combinations of the composite structure wide range of experiment can be performed.
