That does look like another option but then I might still go with the Inkbird if I could find a good price as it does have some potential, depending on what we might each need. I live in hot country and cooling a tank does sometimes become a problem as well as needing heat at other times. That makes the Inkbird with separate plugs/settings for heat and cool a value worth going for in my case.
I find the temperature setting on it so much more "readable" as they have much better English than the cheaper one I've used. It is possible to finally sort out the directions but I have made my own set of directions to avoid trying to read their version!
For holding the temp, I find both are plenty good and don't worry that but larger tanks are easier to keep steady than smaller. I tend to set the heater up and get it set to the temp I want but they vary quite a bit and really have no number, so I set them first and then set the controller just a bit off that setting and the combo can keep a big tank steady enough to never vary off more than one degree. I have one tank that set off the normal path but with the nice big display, I just looked that way any time I passed and got used to seeing 76.4 until warm weather.
Each tank works a bit different but I find in this area and the way I keep my tanks with lights under canopies and canisters underneath, heaters even near the recommended size is just a waste as I get so much heat from everything else. Some tanks, I set a small cooling fan gizmo on the back and let the Inkbird decide if heat or cool is needed. Junk computers are free and easy to pick up here and have some really nice small fans in them. Combined with the super dry air, I can get all the cooling I need from evaporation.
- Interesting idea on sealing the thermocouple (probe) with a straw. I was thinking silicone might be as good or Plastidip even better!?
(might make lesser expensive models that indicate the probe is not to be put in water, to work fine in water?)
Note: I currently have a couple of the Finnex Temperature Controllers, one to a 500w titanium heater (60g) and the other to an 800w titanium heater (110g stock tank, basement). They both work GREAT.
I do lots of repair work and it has "trained" me to do everything I can to prevent trouble as it is much easier than fixing something after it breaks down so it came natural for me to look at making sure these probes last after the first one went bad> I torn it down and found water in it so looked for better options and there really are several things that I like for different tanks and where I want the probe to hide. For longer tubing, there are a number of things, if we keep our eyes open.
The small grey flex tubing for water supply to sinks, can make a nice waterproof straw for deep tanks. But the long soda straws from "burger heaven" are really easy and cheap.
