Compost Thermometers

Sort by:

Temperature is a key variable in compost making. The pile must get hot enough to kill bad pathogens but not too hot to retain the good ones.
Groundgrocer are exclusive agents in Australia and NZ for high quality US-made ISO 9001 certified REOTEMP compost thermometers.

Choose a probe length to reach the centre of your pile or windrow. These meters are good for measuring soil temperature too. We highly recommend adding a probe handle.
