Re: Density Base OHP and Stouffer

Hi Sandy,

I probably need to calibrate mine too then!

After our exchange of last week with different readings from your
361T and my Gretage D-200II I went back and checked my calibration.
My densitometer was actually off off by + 0.01 in UV reading the
Gretag calibration step wedge. If I adjust the reading down by that
amount my numbers agree with Stouffer Industries for the step wedges.


Best Wishes,
