The present setup is designed to study the critical heat flux of a given nichrome wire. The setup consists of temperature controlled water bath with help of Digital Temperature controller. Temperature of the water bath can be varied from ambient to 80°C to achieve different environmental conditions for nichrome wire. Test heater wire is placed in the bath & voltage is varied by variac provided. The system is complete with digital temperature controller, voltmeter, ammeter with peak hold facility & voltage control.

•An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.

•The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Paint.
