Description Notes

Brass demonstration piece to show how an arrangement of thermo-couples can produce an electro-motive force. Thermo-couples are held within brass tubing at the top of a stand, the height of which is adjustable with a knurled clamping screw. Heat is introduced into the thermo-couples via a funnel shaped tube that push-fits onto the apparatus. All tubing is detachable and slitted.

Condition: good; complete.
