Bi-Metal Strip
Bi-Metal StripThis consists of a bimetalic strip 220 × 18 × 1mm attached to a wooden handle. Gentle heating causes the strip to bend into a pronounced curve demonstrating that different metals expand by different amounts.
BI-Metal Strip Kit
BI-Metal Strip KitA class kit which consists of 10 bi-metal strips measuring 100 × 8 × 0.5 securely attached to wooden supports, 50 × 35 × 12mm. Students can produce thermostats while revising simple circuit ideas in an excellent investigation.

Leslie’s’ Radiation Plate
Leslie’s’ Radiation PlateThis apparatus allows the demonstration of the dramatic differences in radiated heat from various surfaces. Being electrically heated it is more convenient than some of the more conventional methods involving water or Bunsen flames.
Thermal Insulation system
Thermal Insulation systemThis apparatus permits the simple or detailed study of the benefits of using house insulation to reduce energy consumption. A thermostatically controlled hot plate is provided with provision for monitoring the input power to the electric heaters.
Thermistor System
Thermistor SystemThis apparatus contains an NTC bead thermistor with a nominal resistance of 4.7kΩ in a glass tube with electrical connection made by means of 4mm flying leads.
