Aquarium Thermometer, 2 PCS AikTryee Fish Tank Thermometer, Reptile Thermometer, Terrarium Temperature Meters Gauge, LCD Display ( ℉) for Vehicle Reptile Terrarium Fish Tank Refrigerator

These thermometers work amazing. They read the temperature on the probes pretty accurately. When both of the probes are near the same area, they read the same temp which means that the temp is accurate (the temperature is off by .2-3 degrees which is totally normal because it can fluctuate). The only thing I disliked is that it was on when I got it, and that the suction cups were hard to put on the probe. Other than that these thermometers work wonderfully for a cheap price and they can read pretty high temps!

Absolute junk. Spend a little more and save your fish.Purchased these to install in three saltwater tanks (29g, 32g, 55g). Straight out of the package, the batteries were dead in two of the thermometers and the battery door on one was broken. I replaced batteries and taped the door on and installed them in the tanks. I discovered the temperature reading were off on all four thermometers. They fluctuated between 4 degrees and 15 degrees off when they decide to work. They will also shut off about every every other day for no reason.Terrible buy. Find a better product.

These are easy to use.And actually very accurate. We tried them both in a variety of situations and locations and compared them to regular thermometers and we were surprised with their accuracy.Our main concern was the amount of heat in our hot water heater.We would recommend this for anybody who needs such devices. They seem to be well-built and sturdy and useful for several applications. And reasonably priced.

I got both of them in use seemed to be ok. Both read water temperature good. Both quite working within 24 hours of setting them up. Change batteries in both still didn't come back on. Money wasted. Would buy again.

I really liked these gauges however they only indicate up to 199 degrees and then go to "HHH" above that 199 degrees. I use them both on my honda SxS. I zip tie one gauge sensor to my radiator inlet elbow and the other one to the bottom tank outlet elbow. It helps to determine my radiator efficiency. I really need them to read up to 230 F. Otherwise I would give them 5 stars.

This battery operated LCD thermometer works great for many applications. I wanted to know the Ambient Temperature while I was riding my motorcycle. For daylight use, this was a quick and easy install. I have another one that's the same size but runs off of 12 volt power and is illuminated, but I just haven't found the time to hook it up. These will work great in the meantime.

They work well and appear to be accurate. Perfect for the project I plan to use them for. But both arrived with dead batteries. They are shipped without a battery stop tab, that little plastic strip that keeps the device off. I guess they were on the shelf long enough for the batteries to discharge. The shipped battery was still at 1.22 volts, but that was not enough to make them work. 2 new 1.50 cells and they were fine. Comes with an LR44 cell, which I replaced with a new 357.

Great two pack of thermometers for the price! Easy to read, very accurate (I compared to my Fluke meter with a thermistor) and the suction cup holds the business end of the system securely under the water level. I have one in my tank and one in my sump, and the cables are long enough the I have them side-by-side on the end of my 5’ tank. Great buy!
