Intex - Pool Thermometer

Works OK but could do with a bit more weight on the bottom as it does not float completely upright

value for money pool temp. Graduated by deg only and takes few minutes to reach temp.

Excellent value for money

I checked this against a certified thermometer (accurate to 0.1C) and it read 0.5C out. This is good enough for most purpose, and it is now in use in my swimming pool.I also bought another one from Thermometer World (with orange float on top) and that was also 0.5C out, though in the other direction. Though it is a bit more expensive I prefer that one for having a longer scale and clearer markings (and for the fact that I was able to recalibrate it accurately and remove the float for compact carrying in my swimming bag - see my review of it).

I use this in the sea, and it's great to see the difference in temperature from one area to another. Also, living in Scotland, when non swimming people tell me "Oh I could never do that, it must be freezing", I can tell them, "no it's actually 16 Celsius, 17 Celsius or even 18 Celsius" last weekend.

Seems accurate enough and easy to read. Maybe it's my OCD being nit-picky, but why couldn't they have weighted this so it floats vertically, rather than at a wonky angle?  13 Pieces Geometry Set Rulers Compass with Protractor Math Tools Set for Students  If this kind of stuff doesn't bother you in the slightest, then feel free to mentally add those missing 2 stars to my review score. 13 Pieces Geometry Set Rulers Compass with Protractor Math Tools Set for Students

Seems reasonably accurate when held underwater but, left to its own devices, it does not float vertically. There is insufficient weight in the bottom. So it floats on its side and measures the temperature in the top few millimetres of water - which is not really what you want a pool thermometer to do.

I bought this for my pond, temp works fine but it floats horizontally not upright .water gets under glass then hard to see temp.
