  • 4 — крышка внутренней ёмкости
  • 5 — крышка всего калориметра
  • 6 — коническая воронка с трубкой, через которую талая вода из средней емкости попадала в накопитель для последующего измерения её количества
  • 7 — трубка для отвода талой воды из внешней ёмкости
  • 8 — решётка, поддерживавшая лёд в средней ёмкости
  • 9 — сито, помещавшееся под решёткой 8
