NOT Accurate by Anth

Comments: Mine's off by at least 4 degrees. I have the cheaper merc style one in the tank also and its always accurate. I'd just stay with those. This digi one is a waste of money. I would not recommend this product to my friends.

Great little Thermometer by JOSHUA KANE

Comments: This is a great little thermometer. I had an old mercury one in my tank, and this is proving to be much more accurate. It is also very easy to read. Yes, I would recommend this product to my friends.

Comments: I bought three of these and all three display different temperatures (75.4, 80.2 and 80.5) in the same tank in the same location. They are 5 degrees off from one another! Yes, I would recommend this product to my friends.

Cant Trust Them! by KEVIN KEHRER

Experience Level: Intermediate

Posted on 12/5/2007 from HIGHLAND, IL UNITED STATES

Comments: I have 3 of these and recently moved everything into one large system. I had one in each tank on the system and they were all a few degrees different, I placed them all in the same tank right next to each other and the same result. I really have no idea what my temp is... Yes, I would recommend this product to my friends.

Not Accurate! by Complexity

Comments: I bought several of these, but became confused when tanks sitting side-by-side showed temperatures of 3+ degrees difference. So I decided to put 3 of the Coralife thermometers in one tank to figure out which one was the "bad" one. What I discovered, after testing about 7 of these, is that they varied as much as 4 degrees when the probes were side-by-side in the same tank. While some variances are to be expected since you cannot put the probes in the exact same location, probes 1" apart from each other should not have a variance of 4 degrees between them. I observed two thermometers display a strange behavior in that they would reach a certain temperature, such as 80 degrees, and then suddenly go into a 'free-fall' of displaying various lowered temperatures until it had dropped to 79 degrees (the drop in temperature took only about 20 seconds). Then they would slowly increase back to 80 degrees (takes about 5 minutes) and then go right back into the free-fall to 79 again. Two thermometers did this at least 3 times in a row. While these thermometers were behaving in this manner, the other thermometers with probes only 1" away would display temps of 81 degrees and higher without any of the 'free-fall' behavior. Very odd. It got to the point, I literally had no idea what the temperature was in the tank even though I had 4 Coralife digital thermometers connected to it. For now, I've had to find the ones that appear to agree the best (within 1.5-2 degrees of each other), and then put 2 of them on each tank. Then I average the difference between the two to guess at what the temperature might be. However, I'm finding that the regular, cheap hang-on glass/mercury thermometers are more accurate and display the temperature faster (important for matching temps for water changes). I will be replacing these thermometers and highly regret buying them. I very strongly recommend avoiding them. They claim to only have a variance of 2 degrees, but my experience indicated up to 4 degrees variance between them. I would not recommend this product to my friends.

Get what you pay for by SaltyDoc

Comments: It works fine, but it is not very accurate. It is definitely off by +2 degrees, if not slightly more. I guess if you keep this in mind then it doesn't really matter. Yes, I would recommend this product to my friends.
