Model 1505D and 1515D Pressure Chambers are a new release with changes that most users will appreciate. It is a 100 bar digital instrument fully enclosed in a sealed case with an external tank (1505D) or easily removable tank (1515D). It is similar to Models 600 and 615 except higher pressure and digital readout.

The Control Valve and internal piping have been upgraded 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).

Models 1515D is highly portable on quad bikes or can be carried over the shoulder.

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.
