Is this a floating thermometer or does it sink?

I haven't used it for a while but believe that it sinks. I keep it on my boat to measure the water temperature for my logs.

I use a photo thermometer and it has always matched so far. Although if this thermometer is in direct sunlight it will give a false high reading so make sure that you place it in a shaded area of your aquarium.

It's designed to sink. And when done, turn the power off while it's still in the water so it cools down. Then take it out. Great light, best I've ever used.

The red stuff in the bottom of the thermometer is like a wax plug but I'm sure that it must be somewhat liquid because the red stuff goes up and down as the temperature moves. Hope that helps. You will know if it is broke if it doesn't change temperatures when you take it out of the water. It should change as the temperature changes. If it doesn't move at all then it is broke.

The grandkids always try to dunk it. So it can go under, but it is a floating thermometer.

Yes this will float on the water if you accidentally drop it in since it has air inside it and the air doesn't easily get out (it will not instantly sink like a rock). However, I did a test on it (seeing your question) and if you leave it in for a while, it will start filling the inside with water and start sinking (I left it for an hour and it was 1/2 filled).

You don't need a float. Just hang the wire over the side and let it touch the side, it won't burn it. I use it to heat the water in my hot tub and it works just fine. It touches the bottom and nothing melts.

On the back of the sensor, there are 2 sensors or contact points. When water touches the 2 points it completes the circuit. It is designed to sit in a drip pan of some sort. You would have to make your own mounts. I believe it senses ambient temp.

It's solid plastic and there are metal sensors that determine the temp of the water. I haven't noticed any water on the inside of this thing. I take it out of the tub after I determine the temp, so it's not constantly immersed. I do this more to preserve battery life than anything else.

I would say "no" that it is not meant to be immersed in water. I suggest for that, you look for a "pool" type thermometer instead. I hope this helps.

My does not sink at all. Do you have the hook up strap run through the yellow loop that is on the front.

The thermometer rests snugly inside of a rubber (or silicone?) gasket. There is a very small hole in the gasket for the end of the thermometer to go through, but it's very small.

I noticed that the temp display had very subtle shading to distinguish between the heat settings. We depend on wrist dipping and a toy ducky which has a temp readout that is easier to see.

Yes, ours is tied to a post inside the L-shaped part of our dock and is kept there from May to September. However our small lake doesn't allow motors, so doesn't have large wakes that might cause the thermometer to get banged around. The plastic exterior is pretty sturdy and has survived handling by our young grandchildren, at least for this first year we've owned it.

It all depends upon how you set up the site flow. It isn't much. And it floats. I had to hold it down with my heater.

I don't know if it floats. It was too small for what I needed, so I packed it away and don't know where. Sorry.

This is interesting queston. I put a slat in my bathtub and I see it floats not sink...is it help for you?
