Elmo Instruments Industries Karan Puri, Ambala, Haryana

Set of two 75 mm diameter speakers for use in acoustics experiments such as interference. The stand is designed to avoid concealing the speaker and obstructing the sound propagation from the cone. Frequency range, 0 to 5000 Hz; maximum efficiency at 400 Hz; output, 0.2 watts; impedance, 45 Ω.

This is a simple device showing the magnetic effect. A simple rod mounted on a round plastic base . when two permanent magnts are introduced in the rod with the opposite poles facing sides shows the magnetic effect.

This is a simple rugged plastic bell.and is ideal for a wide range of experiments.included sturdy pressed plastic box. Pivoted armature, double coil. And nickel plated gong.

These cart are tough enough to withstand the worst .more importantly their axles are aligned to insure that they roll a true line without deviation, minimizing drag and making for accurate data. They give superior data for all quantitative kinematics experiments.

A Large 3 -12 digit LCD display and low cost makes this meter ideal for begining electronics courses. Meter includes coltsohmsresistancecurrent plus transistor and diode testing.

Elmo Instruments Industries is engaged in offering a wide range of physics lab equipment in India.

In addition to being an excellent standard of resistance, this box is particularly good for use with AC and DC bridge, Wheatstone bridges and potentiometers. Its wide range of resistance, from 0 to 1,111,110 ohms, makes it possible to get any value bu 1-ohm steps and its accurate to within + - 0.5 &(+ - .1 ohm). The box consists of six smooth operating rotary switches in decade sequence.

This Ripple Tank comprises of a molded fram with an acrylic window. Scratch resistant supported by adjustable legs.

This rugged, sensitive electroscope can accept various accessories to change its capacitance. Sensitive aluminium vane is balanced in a vertical position on a metal support which is insulated from its base. The vane is easily observed and projected on a chalk board (light source not included). On which an arbitrary scale has been marked.

They are made by connecting three single phase together. The brush arms are moved by a common shaft. The three winding are connected in a star and the star points connected to the neutral wire system. Thus, a 3 phase voltage variable from 0 to 440 volts is obtained.

Our basic ticker tape timer is AC synchronous, producing dots at precise intervals every 160th second making precision measurements possible in all kinematics experiments. The body is finished. And requires a 6 V AC or 110 V AC source. Supplied with one roll of 13 mm x 154 mm and package of carbon disc.
