thermometers?

[paddyedgar]

I find the small glass thermometers that fit inside the tank not easy to read and accuracy is questionable. I recently bought two identical digital
and found that the readings between the two were as much as 3.0C different. Can anyone recommend a better one and where can I get them?

If you can find a SERA glass thermometer that would be best, they around 3x the height of the JBL or generic glass thermometers and much easier to read, they all seem pretty standard as well, i have 9 all all read to within 0.5C when placed in the one tank.

thanks for that ILLUSON. I will certainly try to get hold of one. Unfortunately LFS are ordinary.
