Leaf pressure chamber 615

The Model 615 Pressure Chamber Instrument has quickly become a favorite for growers making routine water measurements and scheduling irrigation. It 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-Terain-Vehicle (ATV). The results of these requests is the Model 615 Pressure Chamber. We have recently (June 2011) updated this instrument with some 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. This stainless steel valve is more durable and has a more robust packing therefore providing longer life. 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 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.
