  • Fairly accurate temp readings, calibrated using ice bath
I wanted to see how accurate this digital thermometer was so i calibrated using a ice bath. One of the digital thermometer measured 33.2 F (assuming 32 F for the ice bath). This is fairly accurate since it is +/- 1 off. The other thermometer measured a bit higher (33.7) so they are not the same but close. My el cheapo analog thermometer from APi is more accurate in terms of the ice bath at 32F. But all good since it is within tolerance. ... show more

  • Good thermometers for aquariums
These are the best thermometers - both for functionality and for the price. They work well and the batteries last a looong time (especially if you turn off the screen when you don't need it). Mine have all gotten a little wet and still function great. Easy to read, buttons are easy to press.

  • Accurate
I’d say it’s pretty accurate, slightly off but good for the price

  • Good product
Bought this item to verify accuracy of another item purchased and it works great. Both items have a similar reading

  • Must have for aquariums
These are so easy, durable, and you can change from Fahrenheit to Celsius. Good deal for the price

  • Good for the price
Good to have for a reference point. Not accurate. I have two and they are both off by about +3°F. It has a power button and a switch to change from C to F. The screen is very dark and makes it hard to see if it's not day time or the lights are on. Sometimes a hassle when the fish room is dark already but I want to see the temps. ... show more

  • Important verification of water temperature
My aquariums hold Sea Monkeys (R) and Giant Triops (tadpole shrimp). The main tank is freshwater. The thermometers helped me setup the hatching tanks and the main tank. Shrimp eggs hatch quicker when the water, light, and temperature is correct. Since the heaters don't display the water temperature, the thermometers showed how quickly the temperature changed. One unit had a bad suction cup. A deformity kept it from sticking to the tank. Fortunately, a paperclip might work. Seventy-eight degrees is important for life. Make sure your plants and animals are comfortable, too. ... show more
