Most Popular where composting and early planting are important, these meters add the versatility of an electronic sensor which can measure to over 180 degrees. 

Composting:
keeping temperature and moisture in the right range is critical to rapid decomposition as well as the preventing of anaerobic activity and in the worst case obnoxious smells.

Growing:
The TEMP series can be used to optimize germination time and protect against threat of frost.  Additionally it can help prevent chemical and fertilizer application from being ineffective due to incorrect soil temperature.
