For those who need a gauge, I would tend to go with the digital readout as Landarch shows. as opposed to the dial reads.@landarch wrote:I received a "free" compost thermometer through the county extension office when I purchased a compost bin...it did not last more than 2-3 years.

Mechanical thermometers only last a while in the elements before either breaking down or going out of calibration.
Thermometers purchased in stores cannot be calibrated.
Digital readouts use a thermocouple ( two dissimilar metals ) creating mili amps signals that are always accurate.
At least until the electronics go haywire.

Thanks Landarch for the link to that DIY compost thermometer.@landarch wrote:... Here's an interesting DIY digital compost thermometer for cheap...
I have ordered 3 digital refrigerator thermometers from a seller on Ebay. The total cost is around $5 Canadian with free shipping from Hong Kong. Downside is uncertain delivery time ... anywhere from August 31 to October 7!!! Looking forward to making my own compost thermometer.
