Heat Apparatus

With our sustained efforts & experience manpower, we have been able to offer Lee's Thermal Apparatus that is made up of brass mounted on a stand. These apparatus are used to determine relative conductivity of the poor conductors. Our offered apparatus are completely checked by quality experts under strict parameters meeting all the standards. Customers can avail these apparatus from us at nominal rates.

Features:

• Accurate dimension
• Sturdiness
• Optimum strength

• Item Code: PHFAA020

Our organization is actively engaged in manufacturing and trading Simple Linear Expansion Apparatus. The offered apparatus demonstrates Demonstrates the linear expansion of solids and allows comparison of expansion rods of different materials. Comprises cast metal end supports mounted at each end of a horizontal metal reservoir, open at the top, that can take any liquid fuel such as alcohol. One of the end supports has a scale with pointer needle on the outside to indicate the expansion in the rod. Expansion rods supported in the holes near top of both the end supports and can be clamped at the end opposite to that of scale pointer. Burning of fuel in the reservoir causes rod at the top to expand, which in turn pushes the pointer needle showing deflection in the scale. Includes three expansion rods, 1 each of brass, copper and aluminium.

With an aim to stand tall on the expectations of our esteemed clients, we are providing Thermal Conductivity Bars. Ideal for comparison of thermal conductivity of different metals quickly and conveniently. Unique, new conductivity bar set features convenient liquid crystal indicators mounted in robust holders. Comprises four identicalmetal bars of same shape and size, each of different metal – copper, aluminium, brass and steel, held firmly parallel to one another in a rigid moulded carrier with a hole for convenient suspension. Conductivity value of each bar is clearly marked on the back of the support. The sensitive liquid crystal temperature indicators working in low temperature range, are attached to the front of all the four metal bars. The temperature indicators are marked at 1cm interval to facilitate charting the movement of temperature gradients. The rate of heat flow is indicated by timing the colour change across these markers. The demonstration requires only a beaker or container of hot water, thus doing away with open flames, hotplates, or messy “melting wax” method of comparison. Within seconds of placing the ends of the bars in hot water, a visible “heat pulse” travels to the copper bar; the steel bar takes several minutes to conduct the heat to its upper end. Timing the “heat pulses” enables estimation of the relative conductivities and their comparison with the stated theoretical values. Also demonstrates the conduction of heat from a heated bar to its end, if cooled.

Useful for experiments involving heating by means of steam or where continuous source of steam is needed. Made of heavy gauge aluminium sheet to provide sturdiness and durability for withstanding high boiling pressures, with riffled nozzle for steam outlet. Consists of boiler assembly, two rubber stoppers – one solid and one with a hole for thermometer, one sample cup with handle and tripod stand assembly.

Additional Information:

• Item Code: PHFAA120

Demonstrates the convection currents in air. Comprises a sheet metal box with open sliding glass front and two circular openings at the top for mounting glass chimneys. On the inner side, below each chimney, a candle holder is mounted. Air heated by a candle placed beneath one of the chimneys with glass door closed, causes the flow of convection currents, which can be observed by bringing a smoldering string near the top of other unheated chimney. Supplied without candles.

• Item Code: PHFAA150

Useful for qualitative experiments in thermal radiation. The results can also be quantified using a suitable radiation sensor facilitating investigation of radiation from different surfaces at a single temperature or radiation from a single surface at different temperatures (Stefan-Boltzman's Law). Comprises a sheet metal cube of sides about 130mm with opening at the top, for pouring in water and inserting a thermometer through a holed rubber stopper. One each of the four vertical faces is finished black, varnished, roughened and polished.
