So no worries at all. To mention, Digital thermometer look more hightech and more readable so consumers will usually fall for it... Including me My Digital read out with Fan turned ON is 26... super hot day, will hit 31... |

Bro, dont worry... there is no vapour in the thermometer the empty space in the thermometer is vacuum. Mercury don't vapourise easily.
Why difficult? I have play around with mercury in my secondary school science lab (Secretly). Quite easy to separate from water... Unless the mercury got sucked into the filter or got sucked into a power head and beat up into micro size (Your fish will likely die when it ingest the floating Hg). then just change 100% water. Or you have gravel then headache, Last edited by Limsteel; 05-07-2008 at 12:53 AM. |
