great thermometer idea (I think anyway)

[Desertdrifter]

I bought a digital thermometer ,one that shows inside and outside temp. with memory.($16.00) taped the outdoor sensor to the side of my tank with some soft foam insulation over it.it is always 2 deg. cooler than the actual temp. but real accurate.saved my bacon twice so far ,once I was pumping water out of the rong storage tank ,the unheated one! once I accdentaly unpluged one of my heaters. 150 gallons takes a long time to heat up so you dont want it to get cold . digital thermometers show changes fast. also shows if there is a problem when you are not around. like at night when the light are off and you have the temp in youre house down.

great which model and where did you get it?

any hardware store they are real common its just a household thermometer that shows out door temps and has a remote sensor .

I use to put the outdoor probe directly into water. The outdoor probe suppose to be hermatically sealed. ( the great thing is it measure max and min) It gives you an idea of how much temp swing at wc.
I work quite well for close to a year. Then it stop working submersed.

At the moment the digital thermometer actually is measuring outdoor temp and indoor temp.

I use the Taylor instruments 1420 indoor outdoor thermometer, $8.81 usually accurate to within 1 degree F.

:bounce2: :bounce2: I'm using the Lifeguard digital temp alert on the 2 main tanks & the QT. Guess my paranoia is showing cuz they're more expensive than RandalBs idea, which I think is a good one. These have a top & bottom temp to set & when exceeded in either direction sets off an alarm. I need extra help cuz I don't think to check temps regularly, always in a hurry, & this eases my mind (what mind?) :blockhead: :blockhead: anyway, JMO (guess my age is showing again, hahahahahaha! lol, Dottie ::) ::) ::) ::) ::) ::)
