The Model 1505D Pressure Chamber Instrument is a new release with changes that most users will appreciate.  We have upgraded the Control Valve and internal piping to now allow direct connection to Nitrogen Cylinders with 207 Bar/3000 PSI pressure.  The instrument is fitted with a 100 Bar Digital Gauge that offers features such as backlighting and multiple pressure scales such as (Bar, Mpa and PSI).  Download our Users Manual to see all gauge features.

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 1/4 inch in diameter down to a completely closed position.  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 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.
