SmartChoice Premium Stainless Steel Soil Thermometer for Backyard Composting - 1.5 Inch Diameter 0-220 Fahrenheit Dial, 5” Inch Temperature Probe for Indoor and Outdoor Gardening

I bought this thermometer to do A/C work on cars. I like the blue zone from 40-50 degrees and after replacing half the system on a 20-year-old van the thermo shows my temp fluctuating between 37 and 44 degrees as the compressor cycles on and off. I cannot vouch for the accuracy, but this is what I was expecting/hoping for. This is a good tool to have around.

So, I've now used this thermometer several times - and I'm confident that it is telling me the truth.I try to measure the soil temp in the morning. Don't want to get too excited about warming & plant too soon!I also check that the thermometer appears to be reading close to the air temperature before I put it in the ground for a sample. Also trying to be consistent with how deep I put it. Doesn't need to be too deep, 'cause seeds aren't buried that far!Do allow several minutes in the ground to get an accurate reading - I judge by waiting for the needle to stop, and waiting a bit longer.

Bought this to test automotive AC. Works perfectly for that. Pretty sure it’s for AC, not compost. Although it would work for that or a meat thermometer. Very happy with it.

The thermometer appears to be accurate. The large display is great. At first I thought it seemed a little flimsily, however was able to insert the probe 2" into hard dirt with no issues. All in all a nice item.

I keep it in my ac vent to keep track of the cooling temperature. The red band between 40-50 degrees is right where I want the temperature and is very easy to tell with the red band.
