Heavy-duty, stainless steel construction with easy to read dials.
Unbreakable plastic crystal. Measure temperatures between 0 deg F
Very accurate, +/- 1% of scale.
The 36" is ideally suited for monitoring large compost bins or windrows, has heavy-duty 5/16" diameter stem;
use the 20" for typically-sized backyard compost pile.
This is a beautiful, sturdy tool. It reads quickly and it really is well built. It comes with a brief composting guide on the packaging which is is great for beginners.Review by Stephanie (on 11/25/13)
