Thermometer

How do you read those stick on black thermometers?

My friends gave a little bigger terrarium(I think 15 gal?) that they don't use and it has the thermometers already on it on both sides, but it has 3 different squares that are "lit up" or "colored" at one time, so I don't know what the real temp actually is.....

It's only a guess but I would think it's the highest temp. shown.
The lower temps. just show up as a gradient temp. view.
If I'm wrong I should have kept my mouth shut.

Those ones aren't very accurate.You'd be better off with a digital one.

Emily,
Do you know what brand thermometer it is?

In addition to those two stick ons, I have a..um...not sure what its called, but its like the kind with a dial, nondigital whatever it is. I'll have to check out the digital ones though,

Emily,

Hm, no I don't see a brand name on them.

Can you post a photo?

This is the best I can get, at least for now. His cage is on a shelf type of thing with a ledge all the way around and I have to use my laptops cam for now to get pics so its hard to get a better one.

The stick on liquid crystal thermometers I've got tend to have 3 or 4 blocks coloured at a time, the one in the middle will be green and the ones either side are yellow. The temperature is given by the block that is most green. So block starts off black, as the temp gets close to the block's set temp it starts to yellow, then green when the right temp, then as the temp goes higher it goes through yellow to black again.
They aren't terribly accurate, but a useful "at a glance" indicator. It's also worth reminding people that most of the digital reptile thermometers have an accuracy of +/- 2c... Just because they read to 0.1c it doesn't mean that they are accurate to that level, it just means that they are more consistently inaccurate. It's also worth pointing out that garters don't require set temperature with a tolerance of less than a couple of degrees.

I'm still planning to get a laboratory grade "mercury" thermometer to calibrate my digital thermometers.

Thanks Chris.
