PAIZOO Aquarium Thermometer LED Digital Thermometer for Fish Tank with USB Power Highly Accurate Waterproof Temperature Gauge with

I was skeptical on whether this would last very long in an aquarium. Has been in the water for many months and have zero issues with it! Read more

This is by far the best thermometer for the aquarium. I have used many other types but this one is the easiest to read. Nothing else (particularly the LCD types) begins to compare. Read more

Video cams placed accurate in front of tank will see clearly the temp reading.even in darkness with infrared cams. And that’s important when I am away. It gets too hot in Vegas. Fortunately I also found a way to activate my AC & HUMIDIFIER when away and the webcams indicate it’s dangerously hot and aquarium temp is rising quickly. I can do math. No other thermometer works both dark and light or without having to press a button my tank. So this one saves my fishies life. If only I could find one that notifies me on my phone when temp goes low or high. I’m sure they are out there to find. For now this is a lifesaver, literally. I’ve used it a month so far without it failing to operate. It’s plugged into a backup battery along with heater filter and fogger/humidifier. This was one answer for when you have no one to watch your fish while out of town. Read more

You will find an inaccuracy of 1.2 to 1.6 degrees Fahrenheit consistently. The small provided suction cups are inadequate and the thermometer comes loose. The two things that this product should do don’t work to a reasonable expectation. Read more

I'm giving this a good rating but I never really used it. I bought it with the express purpose of using it for air temperature, but it needs water to work right. Stupid me. I had to return it. I didn't test it in water but the quality device appears to be excellent. Read more

I have purchased and wasted lots of money going thru several thermometers in the last couple of years trying to find one that is actually somewhat accurate and FINALLY found one. This one is dead on!! Occasionally I see it going off about .1 off; but I will take it. I can trust it showing me what the temp actually is in my aquarium. So easy to read. If you have been in the same boat as me and wanted something that works, give this one a try. Read more
