[quote:d299504eff]I got them from aquariums alive in nerang for $15 each[/quote:d299504eff]
Ash is talking about the digi ones
[quote:d299504eff]
sorry $3.95 at aquarium warehouse[/quote:d299504eff] I take it thats the glass ones.

Matt is right about the mercury too.  8)
Mercury has been used in thermometers since 1714 & only a chemical solution is added to kept the mercury from sticking to the tube of the thermometer. So I'd say it would be spot on, I have never had variances in glass thermometers.

I have seen someone do a test on the digi therms & all gave a different result, 2 degree difference.
To me its like heaters, made in mass, to a setting so there will be variances.

Frenchy :D

[quote:4ed385febe]and how long were the glass thermometers left in the tank before reading?[/quote:4ed385febe]
dyce - about 3 days

kongiwolf- all tests were done in the same tank , with the thermometers stuck next to one another, trust me they are FUBAR.....

Matt, no where did I mention 'mercury thermometers' and yes they (mercury thermometers) are very accurate
But the thermometers I am referring to are the [u:4ed385febe][i:4ed385febe]cheap [/i:4ed385febe][/u:4ed385febe]little glass thermometers with the [color=red:4ed385febe]red[/color:4ed385febe] fluid in them.
This red fluid is not mercury.
Mercury has not been used in these thermometers for years due to the dangers of mercury poisoning when they are broken.Its is an alcohol liquid.Dont believe me? grab a hammer and crack one open and smell it.(i do not condone the previously stated act and any personal injury caused to others or yourself from carrying out such an act, i take no responsibility for - go see ya mumma)

Does your calculator give you incorrect answers when the battery starts to die? -no
The digital thermometers will keep reading the correct temperature even when the battery starts to die.All that happens is the LCD display panel starts to get fainter and fainter untill its unable to be read. I know cause one that I got of stevey had a dud battery (thanks steve :roll: )and did exactly that.


anyways, I know which I will be using on my tanks from now on.... 8)

They can in fact give wrong answers, though you will find it more often with solar power models giving you  really quirky readings at time of low power (ie not enough light), on both counts from experience not a friend of a friends aunts mothers 2nd cousin on your mothers side.  ))o

Sheesh I was only pointing out certain measures to make sure it was a valid test, dont get your panties in a knot :roll:
