One of our Engineers giving a demonstration to our client at a Government College.
The apparatus shown above is a Physics Apparatus known as Brewster’s Angle.
• It helps to study Optical Polarization by Reflection.
• The essential elements of the apparatus consists of a goniometer, a laser light source capable of projecting a light beam that is linearly polarized in its plane of incidence, and a pinhole photo detector with output measurement unit for detecting and measuring the intensity of light reflected.

COLOUR MIXTURE APPARATUS
• Colour mixing takes place when two or more colours come together to form a different colour. This apparatus demonstrates how different colours of light form- from the three primary colours. The three basic colours for mixing light are red, green and blue.
• The apparatus consists of a circular metallic disc graduated into different degrees and operated by a motor in a concealed box-like arrangement. The speed of the motor is adjustable.
• Colour discs of red, green, blue and yellow. The discs are cut in such a way along the sector that they can all be slipped into each other.

DIGITAL REACTION TIME APPARATUS
• Also known as Chronoscope
• It is an apparatus for measuring reaction time to both visual and auditory stimuli with a provision to vary intensity of stimuli and with facility for lateralisation of sound to the right or left ear. The instrument is being used for the study of reaction time in normals, smokers, diabetics, psychiatric patients and neurologically afflicted patients.
• Reaction Time Apparatus gives simple discriminatory and choice reactions for visual and auditory stimuli with built in Chronoscope. It features four stimuli, two response keys and a ready signal. Switches for selecting right or left response key for any stimulus is provided. Chronoscope is a 4 digit chronoscope with least count of 1/1000 sec, works on 230 volts A.C.

MEMORY DRUM FOUR VARIABLE SPEED ELECTRICAL WITH MANUAL
• A memory drum is a piece of laboratory apparatus used to present stimuli in a controlled manner in memory experiments before the advent of computers. Items to be learnt appeared one at a time in the aperture of the drum as it was rotated, either by the experimenter or laterly by timed inputs from a motor.
• The Electronic Memory Drum is a very useful, versatile and accurate instrument. It can be used in most of the Learning, Memory and Forgetting Experiments like Serial Verbal Learning, Retro-active Inhibition. The present instrument (apparatus) operates on 230V 50Hz A.C. and has a removable/detachable drum. One stimulus each can be exposed to the subject at the desired speed (1,2,4,8) with the exposure time 1,2,4,8 seconds respectively. The maximum number of stimulus lists can be SIX(06). The Control Box(Unit) contains an Electric Motor and a FOUR(04) Speed Gear Box and Clutch Mechanism. There are two leavers. Each ON/OFF Switches and two Indicator Lights on the front panel of the Control Unit. Each ON/OFF Switch and Indicator Light is marked with ‘MOTOR’ and ‘LIGHT’ respectively.

METRONOME ELECTRONIC
• A metronome is a piece of laboratory apparatus and is a device that produces regular ticks (beats). More precisely it produces a regulated aural, visual or tactile pulse.
• It can be used to maintain a constant tempo by adjusting the metronome.
• Tempo is always measured in beats per minute (BPM); metronomes can be set to variable tempi, usually ranging from 40 to 208 BPM.

HUMAN MAZE
Image 1: HUMAN MAZE LEARNING POINTED (ELECTRICAL)
• The apparatus is a square shape made of wood. It has 15 rows and 15 columns, i.e. 225 screws are fixed on the wood in the form of points which are connected with bulb and stylus . Bulb does not glow while going on right track but glows while going on wrong track by which error can be known.

Image 2: HUMAN MAZE LEARNING POINTED ELECTRICAL WITH RESET 6 DIGIT ERROR COUNTER
• The working of this apparatus is similar to Maze Learning Electrical (Pointed) but in this error can be known by Reset Error Counter along with the glowing of bulb. After every effort Error Counter is reset.

Image 3: HUMAN MAZE LEARNING ELECTRONIC WITH DIGITAL RESET ERROR COUNTER AND TIMER
• This apparatus is the most advanced with ultra modern technology. The tool operates on A.C. Mains. Subject places the stylus at the starting point of Maze Learning. The Digital Timer immediately starts recording time in seconds and its decimal parts. Whenever there is an error the Digital Error Counter automatically records one error in Digital Form. Thus, here in this instrument time and error both are recorded automatically. Both the Digital Timer and Digital Error Counter are Reset Type and have Four (04) LED chips as Display.
• The apparatuses mentioned above come with a Manual and Response Sheet respectively.

HUMAN MAZE SIMPLE ALUMINIUM MAKE WITH STYLUS
• To study the nature as well as progress in learning through human maze. A maze is a path or collection of paths, typically from an entrance to a goal. The word is used to refer to branching tour puzzles through which the solver must find a route that leads unambiguously through a convoluted layout to a goal.
• It is rectangular in shape with grooved routes. There are three tracks out of which only one track leads to the aim. In this stylus is of aluminium, going on wrong track is an error.
• It comes with a manual and response sheet.

HAND STEADINESS TESTER ELECTRICAL WITH IMPULSE COUNTER ( ELECTRICAL SIMPLE ALSO AVAILABLE )
• This test examines the steadiness of the hand and the fingers.
• There is a box on one side of which there are some holes arranged systematically so that they proceed from the widest to the smallest. The subject takes an instrument called the stylus into his hand and inserts it completely and draws it out of these holes successively.
• Whenever the stylus touches the walls of the hole, the impulse counter would indicate an error.
• The Hand Steadiness Tester is also available without an impulse counter. In that case, whenever the stylus touches the walls of the hole, the light point would indicate an error.
• Comes with a manual.
