Model 1000

The Model 1000 Pressure Chamber Instrument is an old favorite we have built for over 50 years. The instrument can be connected directly to a Nitrogen Cylinder containing 207 Bar/3000 PSI pressure.
Research & High Stress Pressure Chamber Instrument

Model 1000 Pressure Chamber Instrument is an old favorite we have built for over 50 years.

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 research due to the large range of operating pressure. It is good for work on high stress level plants, pressure volume curves but can also be used for routine water measurements for crop plants.

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. For more information about how to use the Model 1000, please check our Resources page.
