Description

This electronic gauge gives you the ability to quickly measure the differential pressure underneath a tarp to figure out the exact aeration health of your pile.

Ideal pressure is 1 inch of water column pressure or greater. With this gauge, you can check your pile as frequently as you'd like - our suggestion is once per week.

• 9 volt battery included
• Includes protective rubber boot
• Water resistant
