Model 615

The Model 615 Pressure Chamber Instrument is a favorite for growers making routine water measurements and scheduling irrigation.
Pressure Chamber Instrument

Preferred by Growers for Water Measurement and Irrigation Scheduling

This is the product of customer input. Our customers requested an instrument that was fully enclosed in a dust-proof case with an easily removable tank. They wanted an instrument that was easily hand carried or ready for mounting on an All-Terrain-Vehicle (ATV). The results of these requests is the Model 615 Pressure Chamber.

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.
