About This Product
Solids expand when they are heated and contract when they cool. With a bar and gauge, pupils can see this without measuring instruments. They first check that the gauge slides over the bar or that the bar end enters the hole, then heat the bar and try again. The fit is lost, and it returns once the bar cools. The insulating handle lets the bar be held while it is hot, so the whole sequence can be shown in a short lesson. The Bar & Gauge Brass With Insulating Handle can be supplied for export orders from Bolivia, Honduras, Fiji, United Arab Emirates, Côte d'Ivoire and Uganda.
