Thermometers

[Mbuniac]

Is there such a thing as a good quality digital liquid crystal thermometer that sticks on the outside of the tank :confused: I took several off the rack at Walmart and they all read a different temperature.
Thanks ahead of time, Sam

Are you talking about the indoor/outdoor thermometers with the probe?

Even with regular thermometers I notice several different readings. I usually look at all of them and then grab one of the ones that matches the most other readings.

No, I just mean the little outside the tank stick-on type. That was the way I picked my little glass one in my 29 gal. , I found several that read the same temp. But these at Walmart all had different temps. I just wanted to know if there was a good quality one of that type.
Thanks, Sam
