The Grain Moisture Monitor GM2 specifically designed for online moisture monitoring of grains and its close relative the Moisture Monitor M2 for other products, are part of a line of cost effective online moisture monitoring solutions from Dryer Master®.

The GM2/M2 is now able to incorporate Dryer Masters's® sensor calibration technology in today’s advanced micro controller based information displays. This allows Dryer Master® to provide a low cost multi-product measurement platform.

The system can provide printed records of operation as well as store data to a removable memory module for retrieval to a computer and be connected to a plant wide automation system.

Outputs are provided for activating a remote alarm or trigger a process event such as a shutdown or product diversion when off spec product is detected. Additional signal outputs for transmitting the moisture and product temperature to other automation equipment is an included option.
