I need to know the core moisture content of thick pieces of douglas fir I have. My meter has short pins, it's a Delmhorst J-2000, and I don't want to spend the money for the longer pins.
I know I can use other metal prongs such as nails or long drill bits that I then connect to the meter with alligator clips and wire. Have any of you done this and what how did it go? I've read it's best to use something that is insulated up to the point of the prong.
The pieces are 8" x 8" x 48". The meter reads 10% surface moisture.
I've had them about 2 years, and I think they were laying around the lumber yard for a while before that.
They have not been kiln dried, and I can't find a kiln locally. Thank you.
