Model 600 can be connected directly to a Nitrogen Cylinder with 207 Bar/3000 PSI pressure.


Instrument comes fitted with our most popular sealing gasket size – 1/4 inch Compression Gland Gasket and Insert. This gasket will seal a sample that is up to 1/4” diameter. If you need other sealing options such as bladed grass or other semi-round sizes check our other options.


This is an excellent choice for routine water measurements for crop plants and light research in plants with little to moderate water stress. For extensive research projects you might consider a Model 1000 or Model 1505D due to the large range of operating pressure. The instrument requires a compressed nitrogen source. You can use it in a lab or green house with a large cylinder or buy our light weight Portable Tank to allow for field work.
