PMS - Model 670 - Pressure Chamber Instrument - Manual

Model 670 Pressure Chamber Instrument is unique in our instrument line due to the 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. For extensive research projects you might consider a Model 1000 or Model 1505D due to the large range of operating pressure. The Model 670 can be connected directly to a Nitrogen Cylinder with 207 Bar/3000 PSI pressure.
