The Model 670 is unique in our instrument line in that it has an extremely large chamber. The chamber is 4 inches in diameter and 7 inches deep. We only recommend this instrument if you are working with a large leaf since it takes a large amount of nitrogen to fill the chamber and makes working with smaller samples time consuming. If you are looking at making routine water measurements for scheduling deficit irrigation or explaining plant water relations and do not need this large chamber we recommend the Model 600.
This instrument is now sold standard with a Compression Gland Sealing System. It comes standard with a 1/2 Inch Compression Gland Gasket and Insert. This gasket will seal samples from 1/2 inch diameter down to 3/8 inch diameter. For sealing samples smaller than 3/8 inch the following accessories are recommended:
3/8 inch Compression Gland Gasket (Seals from 3/8 inch diameter down
to 1/4 inch diameter samples)
3/8 inch Compression Gland Insert
1/4 inch Compression Gland Gasket (Seals from 1/4 inch diameter down
to zerio inch diameter samples)
1/4 inch Compression Gland Insert
