The Rapitest Compost Thermometer is perfect for measuring the temperature in your compost. It features a 19" stainless steel probe. The readout is a dial that is easy to read.

It is important to add compost to your garden to maintain and fertilize the soil. When you compost at the optimal temperature, it decomposes faster.
This occurs between 110 and 160 degrees (range is from 0 to 220 degrees). It helps you determine when to add more matter, and when to turn the pile.
