We manufacture demonstration table top meter with interchangable scales, applicable in different physics related applications. The main structure comprises of a primary coil of 200/250 volts. It also consists of a secondary coil which delivers an output of 6 and 12 volts at 2 Amps. The transformer is also provided with a 2 meter cord and plug connections. It is manufactured in a way that it allows easy installation of the transformer. Further the interchanging of coils can also be done quickly.

Transformer suitable for 35 watts sodium Lamp, operates on 250 volts A.C. 5 Hz.

We offer power supply of 12 v, for varied industrial use. It aids in providing optimum power supply of about 12 volts. This is made into a compact unit for easy installation and efficient use. It is available with the following features.

• Compact regulated power supply


• Power supply available in 1.5, 3, 4, 5, 6, 9 and 12 volts at currents up to 1 amps.
• Both D.C and A.C outputs maybe used simultaneously.
• The unit is short circuit and overload protected with 1 amp fuse on the back panel.
• It has molded mains leads and plugs.
• Operates on 220 volts and A.C 50 hz.

We also manufacture rheostats 150 mm, for varied use in industries. It is largely applicable in series resistors or potentiometer. They equipment is of open type and slide wire type. It offers a varied resistance power and current carrying capacity.

It comprises of oxidized nickel and copper is used which provides perfect insulation. Further 3 to 4 mm socket terminals are provided for enhanced functioning. The supports are made of metal or bakelite and is of about 43 diameters.

For showing the principles of platinum resistance thermometer and for accurate temperature measurement using a bridge method such as ‘Cary-Foster’ bridge. The thermometer comprises a length of fine platinum wire of about 2 ohms resistance, wound non-inductively on a mica frame and soldered to stout copper leads. A pare of compensating leads are provided, all four leads being connected to 4 mm, socket terminals. Since the connections are soft soldered, this resistance thermometer is suitable for temperature up to about 150° C only for low temperature work.

We offer spot reflecting galvanometer to our clients. These precision engineered galvanometers provide effective detection of currents. It is ideally suitable for industrial kelvin double bridge and senior kelvin double bridge. Our spot reflecting galvanometer is available with the following features :
