Review on 🌡️ bayite BTC201 10A Dual Pre-Wired Digital Outlet Thermostat Plug: 2 Stage Heating and Cooling Mode for Fermentation, BBQ, Reptile Aquarium - 110V-240V by Bill Forbis

This is essential if you keep a reef aquarium and a good buy when you consider that just buying a digital thermometer with alarm is more than 35 costs US dollars per retail. . Having worked in fish shops for years, I've heard that the number one reason people lose their aquariums (apart from impulse purchases, not quarantines) is when their aquarium gets too hot or too cold due to a heater failure. . This device has a built-in alarm that you can set to let you know when the tank is about to overheat or cool down, giving you time to take action before it's too late. It has a sensor on the cord that allows it to read the temperature away from the heater instead of next to it, and then turn on the heater or fan (or cooler) as needed. It looks like the sensor can be replaced if damaged. The display is large and easy to read, the manual controls are quite sharp (about as technically difficult as reading for a digital timer). Quite a few serious fish farmers have Wi-Fi enabled devices to monitor and control their equipment, but if it's out of your budget it's probably fine and will definitely save you in the long run. I've been using it for two weeks now and overall I'm happy with it. Please note: such devices cannot be mounted inside the aquarium stand near the pallet, mount all electronics away from possible drips and splashes. This will save your hardware and, believe me, it will help you avoid some very nasty shocks. The instructions indicate that it is not waterproof and should not be placed in locations where it can splash or drip. Another plus, they let you use your old heaters that had a broken thermostat and got stuck forever. I would still use a second cheap digital thermometer for backup.
