Compost Thermometers

COMPOST THERMOMETERS

Knowing the temperature of your compost is critical to understanding the stage of the process and when to take the next step.  Armed with accurate compost temperature at various depths, you’ll know the most effective time to add material and water, turn the pile and when it is ready for use.  The Tel-Tru line of compost thermometers work equally well in compost piles, bins or tumblers.

When used to measure soil temperature, you’ll know when your soil has reached the ideal range each type of seed requires for germination as well as when to transplant.

The versatile Tel-Tru Compost Thermometer offers the best combination of the key features experienced users appreciate, such as uncompromising accuracy and durability, providing industrial quality for your backyard.

For effortless insertion use a Tel-Tru insertion handle (Model 1139001) on your thermometer. Our compost thermometer handle is detachable and threaded to fit 1/2” NPT male connection.  It is available bundled with the thermometer or can be purchased separately.
