Pressure Chamber Instrument

Model 615D is fitted with a 40 Bar Digital Gauge that offers features such as backlighting and multiple pressure scales (Bar, MPa and PSI).

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 in 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 larger range of operating pressure.

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.
