Grain Temp Guard – Alarm HT


Over-drying corn or beans reduce your product by 1 1/2% for each 1% moisture loss.

Based on current prices, in a 30,000 bushel bin this costs:

  • $1650 for corn
  • $3850 for beans

Money spent to put an alarm HT probe in the top  (this can be placed after the bin is full) of the bin and one in the bottom would go a long way to help a farmer get control of this.
