Is this a floating thermometer or submersible?

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

Floating, but I have yet to get one that stays waterproof for more than a year

Floating. I went through two other brands that didn't last long and this one has been great.

That's the only thing I've used it for! I dip it a few inches into the water, hold it there for about 30 seconds, and the gauge will read accurate temp.

The wire gauge is 16. As it only breaks one leg of the circuit, I would recommend that you use an auxiliary 2-pole relay in conjunction with the float switch and the motor.. Yes, the switch is submersible. It has worked well for me.

I have 4 of them. They are not submersible that I can tell (never tried) because the battery compartment is not sealed.

I haven't dropped in the water yet, but they say it floats. I don't think it is meant to be submerged.

They say "do not submerge the probe" in the directions. You can call them up on the phone, they are easy to talk to. They might have another idea for you. I had to replace my probe because I got it too hot on the grill. $12.00, and I am off and running again. I like it so much, I bought several for Christmas gifts.

I don't think they are submersible. They might float briefly, but there is a switch and openings to the battery compartment that would ultimately allow water inside.

You need not to immerse the probes in water, rather slightly wet a paper towel and clean the probe. I ran my probe under the water causing the probe not to register in the thermometer. We ordered additional probes, all works well now.

The heater and sensor are fully submersible, the digital control is not (I would assume).

It should be minimally submersible. The IP67 rating means the device is "dust tight" and submersible up to 1 meter for up to 30 minutes.

As others have noted. This is NOT a mercury type thermometer. It uses an internal spring that responds to temperature changes.

I have two, one is exposed to weather. Both have worked flawlessly. I think they are very well made and certainly intended to be mounted outdoors. Submersible, probably not.

I believe its submerge only. There are different resistances in air and water, therefore requiring different design in a motor. This says submersible, so i would take it literally.

I would not recommend any attempt to waterproof the probe. Buy a thermowell(a waterproof metal tube sealed on one end and open on the other) and insert the temperature probe into it to measure temperature underwater. You need to use 316 stainless for a salt water aquarium and 304 for fresh water according to a thermowell manufacturer. You will need some way to mount it also. Here are examples for Homebrew use to give you an idea. https://www.brewershardware.com/Thermowells/ . One thing to note, by default if the sensor fails the relay fails shut. You can adjust this in the settings. See the manual. In my case of cooling Homebrew, the freezer would stay on indefinitely, thus freezing the wort. In your case the heater may stay on raising the temp too high. Again, check the manual for your specific application.

I just bought the 100 watt, and it is fully submersible. It has an all black outer casing, making it blend in to the background very nicely.

It is fully submersible. I use it in a 2 gallon tank for a betta, shrimp, and dwarf frogs. Also extremely accurate. I just took a look at the reviews. First of all, this heater is for a small tank, maybe max of 2 gallons. The room it is in stays about 68 degrees, and this heater maintains the water temp at 78 degrees. Secondly, it has a minimum water line, but the entire unit can be submerged. One reviewer said that he didn't know what the factory preset was, I put it, started it up and then adjusted it up to 78 degrees. I think the preset was probably 72. This was the smallest heater I could find that was controlled with a thermostat.

Seems like an odd question as the description clearly indicates it floats & it is waterproof. ?????
