Image of a series of numbers incrementally increasing from the bottom up. The lower portion of the image is extremely bright making the numbers unreadable.

This sample is at 5 on the scale.

Image of a series of numbers incrementally increasing from the bottom up. The entire set of numbers is visible on this image.
Refractometer 3: This is an example of straight concentrate. Sample is very fuzzy.
Although there is some definite shading, there is no clear line. The whole scale is still visible.
(This is what the base personnel would have seen at the Fillmore accident, had they used the refractometer).

Refractometer 5: Example of a high reading. This sample is at 21 on the scale
(this means there ’s too much salt —too concentrated).
