A steel frame mounted on a heavy cast iron base with leveling screws. Upper end of the rod (under test) 900mm length and 5mm dia is clamped by a 3-jaw chuck and the lower end is clamped into the axis of a torsional drum which can be rotated by putting load in the scale pan passing over two frictionless pulleys. Freely sliding three circular scales graduated in single degrees can be clamped at any position. Three pointers for clamping to the test rod are provided. Complete with three other rods, strings and two scale pans, but without weights

A wide bore glass tube is mounted vertically in front of a scale graduated 0 to 60cm. Zero corresponds to the inside of the closed (top) end of the tube. Air is confined in the tube by a coloured oil contained in a metal pressure chamber which is fitted with a Bourdon type gauge calibrated 0 to 50Lbs/In 2 & 3.5Kg/cm 2 actual pressure. A valve is fitted to the air tube from the pump. As the pressure in the oil chamber is increased, oil and its actual (total) pressure are directly indicated. The tube is of strong glass and securley covered with transparent plastic screen on front. Total height of apparatus 69cm approx.

Specially designed for use with above apparatus cat no. 1040 having five tapings of 6, 12, 18, 24 & 30 volt A.C. and current 3 Amp

The apparatus consists of a horizontal corning glass tube open at both ends. The heating element is a coil about 40cm long of Ni-chrome wire and is wound spirally inside the axis of the glass tube. The element is easily detachable and is encased in a wooden case lined with felt and provided with a hinged cover. "terminals are brought at each end of the tube for the electrical supply. The horizontal tube is connected either by rubber tube or rubber cork to the inlet and the outlet system, each having a short vertical extension to accommodate a thermometer. The complete apparatus is mounted on a polished wooden base board. Supplied with constant level tank fitted on stand but without thermometer & Transformer.

A set of metal rods 300x3mm dia. comprising ten of each, Aluminium (240), Iron (72), Copper (395), Lead (34), Brass (128), Zinc (112) Total of 60 rods.

Made from borosilicate glass, overall length 160mm

A domestic electricity meter adapted to operate single phase 2, wire CI.2 mA x 8.33 A 12V 50Hz 0.01rev/J and dials reading in joules. The meter is mounted on a robust bench stand with 4mm input and ouyput socket terminals.The aluminium disc rotates once every 100 joules with the consumption recorded on three digits calibrated 100, 1000 and 10000 joules per division respectively. The instrument records a maximum of 99,900 joules.

It consists of rising table (as described under Cat. No. 1045 A) and capillary tube clamp (as described under Cat No. 1045) In this case three leveling screws of rising table are replaced by two leveling screws and one long rod to hold the capillary tube clamp.

The apparatus comprises a metal frame, on which three capillary tubes of 10cm long Borosilicate glass and of different internal diameters are clamped with the help of small metal brackets. The 9mm rod is also attached to a metal plate, so that the complete clamp can be held in any stand for determining the surface tension of liquid by capillary rise method.
