Pyrometer
Product Code : EL-H-10397
Quick answer: This Pyrometer is a school heat apparatus for comparing how much different metals expand when heated. It is all metal, with an engraved scale, three test rods of different metals and a spirit furnace for heating them. Students heat the rods and compare the scale readings. Lab Exports manufactures it in Delhi for schools and colleges.

How the pyrometer is used
In school physics, a pyrometer of this type is a comparison apparatus rather than a temperature-reading instrument. Rods of different metals are heated by the same spirit furnace and the elongation of each is read against the engraved scale. Because the rods are heated under the same conditions, differences in the readings reflect differences in their coefficients of linear expansion.
- Set the apparatus on a heat-resistant bench surface with the test rods in place.
- Note the starting position on the engraved scale.
- Light the spirit furnace and heat the rods.
- Read the expansion shown against the scale for each metal.
- Allow the apparatus to cool fully before handling the rods.
The result links directly to everyday engineering: metals that expand more, such as aluminium and brass, need larger allowances in structures, while low-expansion alloys are chosen for measuring tapes and clock pendulums.
