Microprocessor Photo Colorimeter
Microprocessor Photo Colorimeter is a compact and easy to operate instrument for Photo Colorimeter analysis of any concentration.
The output is available on a 16 x 2 line alphanumeric backlit LCD display in terms of %Transmission (%T), Absorbance (Abs.), Concentration (Conc.) and K Factor.
This instrument has 100 sample storage memory and printer output facility for printing data with any dot matrix printer.
The use of microcontroller has made it extremely versatile and accurate instrument.
10 mm path length matched test tubes are used for sample and blank.
The use of high class standard wide range glass filters covering 400 to 700 nm give extremely good results.

Shell Tube Heat Exchanger Water To Water
Heat exchanger is the devices used to transfer the heat from one fluid to other. The shell and tube heat exchanger is two tube single pass heat exchanger. The hot fluid is hot water obtained from water heater. The coil fluid is cold water. The schematic flow arrangement is shown in figure. Hot water enters the lower side of end box, flows through the tubes in lower half of shell and comes to the other end of the shell. It reverses its direction, flows through tubes in upper half of the shell and leaves out. Cold water enters lower part of the shell passes over the tubes between the baffles and leaves out the shell through outlet at upper surface of shell.
SPECIFICATIONS:
1.Shell – 150NB, 750 m.m. long provided with end boxes. a.One end box with divider plate. b.25% cut baffles – 4 Nos. in the shell. 2.Tubes – 4.5mm I.D., 6.35mm O.D.,250 m.m. length copper tubes with triangular pitch. 3.Instantaneous water heater, 3 Kw capacity, to supply hot water. 4.Thermometer for measuring the water temperature. 5.Valves to control hot and cold water flow.SERVICES REQUIRED:

Circuit Breaker Demonstration
Description
Investigate the working principle of circuit breaker type fuse with this demonstration model. The apparatus is built on a robust plastic base and includes resistive loads to simulate external wiring circuits. Applications of the thermal response of bimetal strips and also electromagnetism (movement from a solenoid) are clearly demonstrated in this model. When a 12 V DC supply is connected (not supplied) the LED lights to show that current is flowing in the external circuit and the bi-metal strip can be seen to bend as its heater coil raises the temperature. After a few minutes the bending is sufficient to trip the mechanism and the current path is broken. At any current selection a short circuit situation can be initiated by pressing the red button and this produces an immediate response from the solenoid to disconnect the supply.
