Can I use this device to measure the moisture on a mash product? Like ground grain?

Asked by: Antoniel
Hi Antoneil, Thank you for the inquiry. Using the external mode with pins materials such as soils or powders, the meter readings will reflect average moisture level near the surface. You may need deeper penetration provided by a grain moisture probe. https://www.omega.com/en-us/temperature-measurement/temperature-and-humidity-and-dew-point-meters/p/HGM68-Meter Best regards OMEGA
