Wow! That was lucky! Time to get an Inkbird!Heater failed two nights ago, and the tetras in that tank went down to 12c They were lethargic, pale and not looking good. Pretty sure I’d have lost them if I did t catch it sooner (within 24 hours)

Yes, I did go through calibration with mine - just so I could be sure!On that note, around here most people use simple glass thermometers or cheap digital equipment, with no reliable calibration. They boast about their +/- 0.2 thermostat range, but ignore the probable +/- 2ºC equipment precision.
<"Definitely my choice">, you can get properly calibrated scientific grade spirit filled ones pretty cheaply.On that note, around here most people use simple glass thermometers
I'm a luddite but @sparkyweasel says:I never take any notice of the digital ones, they all become inaccurate over time. Usually I just put my hand against the tank glass. As long as it doesn't feel noticeably hot, or cold, things are OK.
cheers Darrel.... When I worked in electronics, I costed making a thermometer which would give the same accuracy. It would have cost well over £100 for the components at wholesale prices. At the time, aquarium thermometers were under £1.
I also knew that if I built it, it would have been military/aerospace quality construction, and I would have had my mate inspect it to be certain it complied. I doubt if that applies to the £5 ones you can buy now..........
Also, worth keeping in mind there will cold spots in tanks and temp settings on heaters will very likely be pretty inexact. Probably best to err on the side of caution
👍, consistency is more important than whether you are half a degree out imhoYes, I did go through calibration with mine - just so I could be sure!
Although, I think to some degree, it shows the temperature is not always important. i.e. if you thermometer is showing 24.5C, and its actually 23.5C, then you are not going to do too much damage to the fish. It’s going to be the extremities where that lack of accuracy causes you more of a problem.
