The Model 615D Pressure Chamber Instrument is  is similar to our Model 615 except slightly lower 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 34 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 has a bail-spring handle for carrying and comes complete with a shoulder strap to lighten the load in the field.  It has 5 tie-down rings for mounting to ATV or other transportation.  The instrument comes complete with light weight aluminum nitrogen cylinder (20 cubic foot) that is secured with 2 inch heavy duty velcro straps and can be quickly replaced with a full cylinder.  This cylinder can easily be transfilled from a large nitrogen cylinder as shown here in our tutorial page.
