Just What I Needed
Great device. Very Responsive. I was able to take 45 temp, humidity and DEW readings in 30 min. Replication was very accurate.

Can you calibrate this device to insure scientific industry standards of measurement are met?
Hi Mick32,
Thank you for the inquiry. Please forward this request to TEMP@DWYEROMEGA.COM.

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