Model 670 Pressure Chamber Instrument

Listing ID #3284509

Model 670 Pressure Chamber Instrument is unique in our instrument line in due to the large chamber. The chamber is 4 inches in diameter and 7 inches deep. We only recommend this instrument if you are working with a large leaf since it takes a large amount of nitrogen to fill the chamber and makes working with smaller samples time consuming. If you are looking at making routine water measurements for scheduling deficit irrigation or explaining plant water relations and do not need this large chamber PMS recommend the Model 600. PMS have recently (September 2011) updated this instrument with some changes that most users will appreciate. PMS have upgraded the Control Valve and internal piping to now allow direct connection to Nitrogen Cylinders with 207 Bar3000 PSI pressure. This stainless steel valve is more durable and has a better packing therefore giving more life.This instrument comes standard with a Compression Gland Sealing System fitted with a 12 Inch Compression Gland Gasket and Insert. This gasket will seal samples from 12 inch diameter down to 38 inch diameter.
