placed between the frozen products 15 and 18 thereby the bending edge 7 connects the thermometer probes 13 and 14 so that the use of the multi indicator is simple the bending edge 7 is inserted to position 19 and then after freezing both indicators 1 and 2 are placed onto the sides 20 and 21 of the frozen products 15 and 18 as fig9 shows in dashed lines the freezing of a multi indicator according to fig9 is very simple because the bending edge 7 lies between the thermometer probes 13 and 14 and this elongated construction allows a simple handling fig1 to 14 show embodiments of indicators according to the invention by which the indicated position results from chronological freezing fig1 shows a double indicator 8 with the not yet frozen indicator fluids 4 5 and 9 10 arranged in pairs in the four cavities 3 indicator fluids 4 and 5 melt at the same temperature as do the indicator fluids 9 and 10 in fig1 the indicator 8 is shown immersed in liquid freezing mixture 22 a freezing means during freezing at the left in fig1 only indicator fluid 5 in indicator 8 is immersed in freezing mixture 22 which is severely undercooled which results in a quick freezing of the indicator fluid 5 indicator fluid 4 is not yet immersed and does not yet freeze only after inverting the indicator 8 in the direction of the arrow 25 as indicated in fig1 does indicator fluid 4 enter the freezing mixture 22 and freeze affected by gravity indicator fluid 4 flows into and.
