Pinpoint Thermometer question

[swpassion]

I have a Pinpoint Wireless Thermometer and I dont know if it is accrate. I have a coralife thermometer on a different tank and I get 2 completely different readings. The inpoint reads 82 degrees and the coralife reads 76.4. The water feels cool to the touch compared to my other tanks so I believe the pinpoint is wrong. How can I verify if it is reading corectly or calibrate it somehow? The main reason I think the pinpoint is wrong is my heaters are turned all the way down and it is only 67 degrees ambiant temp in the room.

go to a pet store and by a $2 thermometer. That should tell you which one is the most accurate.

The corallife thermometer are not that accurate I would think that the pinpoint one is more accurate. But I do agree with the post above that a cheap non digital thermometer might be the best way to tell which one is more accurate.

I am not sure on the range of the pinpoint thermometers, but a glass of ice water (lot of ice) sitting for a few minutes should read 32 F and boiling water 212 F.
