Patented' dry kiln thermometer...approx. 11 3/4" long x 2" wide. Made by 'Moore Dry Kiln Co. of N. Portland, Or.; Jacksonville, FL.; Vancouver, B.C.; Brampton, Ontario Both thermometers are intact; temperature reading goes up to 240F and appear to be identical. Comes with two wics. This item most likely came from Portland Oregon as it was used in Ashland Oregon at a local sawmill. As I understand it this item was placed in early dry kilns to monitor the amount of moisture in the lumber... that was being dried. Item seems to be extremely rare with little information available on it. Please do your own research before buying this item as it will not be returnable and I will not refund.
