It comprises of a spring mounted steel vibrator arm which carries a contact connected in series with a solenoid. The free end of the vibrator carries a marking point which strikes the paper tape through a disc of carbon paper, thus making the tapes once for each oscillation. It works on 12 volt, 500 mA A.C. Power supply. The complete instrument is mounted upon a polished wooden base and 4 mm socket terminals are provided for electrical connection. Complete with one dozen round carbon papers and roll of paper strip.

For certain measurements it is more convenient to provide sliding motion to the microscope tube across the stage, in addition to all other usual movements. This microscope is very useful in Newton’s ring experiment and graph reading etc. A sliding carriage is fitted on the top cariage which moves at right angle to the horizontal motion by means of rack and pinion. This motion is also graduated in millimeters with a vernier reading of 0.1 mm. Supplied in a superior quality wooden box.

with Square Pillar & Special sliding tube Advanced For the measurement on two axis. for example in the determination of real and apparent depth of liquids.

It is an instrument for the measurement of small lengths e.g. the diameter of Newton’s rings and narrow tubes etc. It consists of a compound microscope mounted vertically or horizontally on a right angles to its axis by means of a screw. The displacement of microscope is measured with verniers which moves with the microscope along a scale fixed to the instrument.

The traveling microscope consists of a cast iron base with machined vee - top surface and is fitted with 3 leveling screws, one being fixed. The microscope can travel horizontally 22 cm and vertically 15 cm with the help of slides. The slow motion knobs are provided for taking accurate readings. Vernier readings 0.01 mm or 0.02 mm. The microscope tube consists of an eyepiece 10 x with 15 mm or 75 mm objective, for holding objects horizontal stage, made of milky cenolite sheet provided on the base.

Because of large cross - sectional area, the heavy type forks have greater frequency, stability and vibrate longer than smaller forks. They are therefore preferred as laboratory standards of frequency and for demonstration and experimental work requiring vibrations of exceptionally long duration. Supplied in a superior quality sunmica top wooden box.
