HDE LCD Fish Tank Thermometer

I saw this thermometer going for $1.00 plus about $2.50 shipping on a popular bidding website. I didn't really trust it to be a real thermometer at that price. So, I looked it up on Amazon.com. For the less than $6.00 including shipping, I decide to pay a couple of bucks more from Amazon and try it. It came in the mail this afternoon.

When I pulled the thermometer out of the package it was set to Celsius. I switched it over to Fahrenheit and it began reading about 82º in my house. I know the air temperature is around 76º. I waited for five minutes as it drifted further and further down but it never got down to what I believe the temperature actually is. It settled in around 78º. I figured a 2º variance isn't bad. Then, I put it in the fish tank. It immediately dropped down to what I believe the temperature of the tank is, according to the cheap floating thermometer I have in the tank. Given that it's designed to read water temperature, that was good enough for me.

I put it on the tank I plan to use it on and I'm looking at it now. The suction cups are powerful, one for the probe and one to attach the thermometer to the tank. I like the digital read out because it's much easier to read than the colored water in the analog thermometers. I can glance at it from a distance and know the temperature of the tank. Not such a big deal right now in summer. But, it'll be great to know in the winter. I now trust that it's fairly accurateaccurate enough anyway.

There's an on-/off switch on it. I'm not sure that's necessary. These type of devices should run a long time on the watch battery it runs on. The battery is replaceable. Turning it off is difficult. The switch recesses and has to be pressed way in and held in to shut it off. At first I thought the switch was broken. But, I used a pen and held it in and it went off. Turning it on was much easier. There's no risk of turning it off accidentally.

I'll report back if/when it breaks. I think with things like this if they work out of the box, they'll work for a while. There are no moving parts. So, I think this is a great deal. It's got to be as accurate as the $3-$4 floating devices you buy at the Local Fish Store. And, if you want, you can hide the display completely, camouflage the probe and make it virtually invisible.

**update**It's been over six months since I bought the first of these. I now have four on four different tanks. They have been rock solid reliable and the temperature reading seems to be accurate matching the set point on my heaters. I am extremely happy with these thermometers.

After getting tired of squinting my eyes to see the temperature of my alcohol thermometer in my reef tank I decided to try a digital version. Like the other reviewer mentioned my digital LCD thermometer arrived in the mail with the power turned on. No big deal. I wish the suction cup holding the probe was black instead of clear like the other reviewer mentioned because a clear suction cup submerged under water appears white. No big deal for me either as I hid my thermometer probe & suction cup behind some live rocks. So far everything works great as I just turn my LCD thermometer on occasionally to check the temperature of my reef tank & then turn it off. Sometimes I just leave it on longer as I still maintain my alcohol thermometer on the other side of the aquarium that I can occasionally still read when it isn't covered by algae. Occasionally I noticed that the thermometer turns on by itself, but that is no big deal to me. Recommended as it generally works great & you can't beat the price considering most digital aquarium thermometers that I see in local stores costs so much more.

Update 4-2-13. I been leaving my LCD thermostat with the power on for the last month & had no problems with it so far. No problems with it turning off by itself. Been so reliable that I removed my standing thermometer.

This thermometer shipped fast and works great! I was recently at a local pet store and the same thermometer was double the price. I would recommend buying it.

I guess I got a defective one. It's stuck with a reading H (degree symbol) F. Tried powering off and on to no avail. Also, impossible to take battery out. Didn't work for me so I can't recommend it.

The HDE aquarium thermometer fluctuates too much to be of any use. The temperature updates about every 30 seconds. Mine has varied from 64 degrees to 110 degrees (really?) within a matter of minutes. In this case, the old adage applies...you get what you pay for.
