RADIANT HEAT SOURCE, LOW VOLTAGE
Click to Enlarge
RADIANT HEAT SOURCE, LOW VOLTAGE (0251)

Provides a low voltage heat radiation source operating on 12V with a current rating of about 8A. Heating coil wound on an insulated former and suspended in a U shaped aluminium enclosure through pillars and is connected to 4mm sockets for electrical connection. The enclosure has lining of heat resistance material on the outside and an aperture of about 28mm. The complete assembly is mounted on a metal rod 150 x 8mm for supporting the apparatus on a suitable retort stand.

JOULE METER, MOUNTED (0252)

A modified single phase, 2 wire watt-hour meter adapted for low voltage working and directly calibrated in Joules (J). Mounted on a wooden bench stand with non-skid base, which also has 2 pairs of 4mm socket terminals, clearly marked for supply and load. The aluminium disc rotates once every 100J consumed, total consumption indicated on rotating digits display with 1st, 2nd and 3rd readings from the left representing 100, 1000 and 10000J respectively to a total of 99,900J. The inter-digit spacing in the left most reading is further subdivided in 10 divisions to approximate the reading to 10J. Designed for use on 12V, 50Hz AC supply with a maximum current of 8.33A. Meter enclosed in transparent casing to facilitate the observation of actual movement of the meter

PLATINUM RESISTANCE THERMOMETER
Click to Enlarge
PLATINUM RESISTANCE THERMOMETER (0253)

Demonstrates the principle of platinum resistance thermometry and its application in precise temperature measurements using a bridge method such as 'Cary-Foster' bridge. It comprises a length of fine platinum wire wound non­inductively on a mica frame and soldered to copper leads. Also provided with a pair of compensating leads, with all the four wires terminating in 4mm terminals at the top. Complete assembly enclosed in a borosilicate tube sealed at the top. Since the connections are soft soldered, the resistance thermometer is suitable for low temperature work up to 150°C.

THERMOPILE
Click to Enlarge
THERMOPILE (0254)

Demonstrates the generation of thermo emf in accordance to the Seebeck effect. Comprises a number of Bismuth mil and Antimony (Sb) couples joined together in series and mounted in an annular metal ring with insulation between them. The Bi-Sb junctions in the metal ring are arranged in the rectangular fashion forming the sensitive area that comprises only of hot junctions, the cold junctions being the thick walled metal body. Terminals provided for electrical connection. A sheet metal conical funnel has a polished inner surface to facilitate the focusing of radiant heat on to the pile junctions and is fitted over the sensitive end of the metal ring to increase the directional sensitivity and to minimize cooling of the pile junctions by extraneous air currents. The complete apparatus mounted on a stable cast metal base through a plated metal rod.
