Physics Instruments

(For deflection magnetometer or tangent galvanometer) Consisting of thick bakelite moulded case of 125 mm dia with black aluminum dial graduated 0 - 900 four times, anti parallax mirror slot. The special permanent magnet (small in size) and a light aluminum pointer (designed for precise reading and maximum damping) supported on a steel pivot by jewel bearing sets. The permanent magnet is designed in such a way so that it has maximum magnetic fields strength.

Consisting of a bakelite moulding case with white aluminum dial graduated 0 – 90° four times. The magnet with aluminum pointer is pivoted at the jewel so as to move frictionless

(Economy Model - Aluminum Fitting) Same as Cat. No. 1078 but with brass cup and brass terminals are replaced by light weight aluminum cup aluminum terminals respectively. Brass leveling screws are replaced by bakelite leveling screws. Supplied with 5” ordinary compass box.

The horizontal component of earth’s magnetic fields can be measured with good precision using this sophisticated instrument. Same as above but with heavy aluminum base terminals are replaced by heavy superior quality 4 mm socket terminals. The leveling screws and brass cup is lacquered in golden colour. The heavy tripod aluminum base is finished with superior quality Duco paint. Supplied with highly sensitive compass box with permanent magnet along with detailed working manual.

It consists of a bakelite moulded ring 170 mm, with three sets of winding - either 2, 50 and 50 turns (depending upon the requirement) respectively, carfully insulated, connected to heavy brass terminals. The number of turns is clearly marked between the terminals. The ring is mounted on a pivoted round bakelite base which rotates on an aluminum tripod base fitted with three brass leveling screws. The high sensitive compass box (with permanent magnet) is mounted on a substance brass pillar and is free to rotate upon it. The compass is 5” in dia and has a scale graduated to single degrees. Overall height is approx. 9”. All brass parts are chrome plated. Supplied with permanent compass box.

Ohm’s meter is designed for measuring the resistance in electric circuits. It is housed in Unbreakable ABS case with clear transparent front cover and operated on 1.5 v AA cell. Size: 100x100x140mm

This galvanometer has a built in lamp and scale arrangement bused in bakelite case.
