Model 670 Pressure Chamber Instrument
The 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 we recommend the Model
600. We have
recently (September 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 better packing
therefore giving more life. Download the Users Guide

more details
This instrument comes standard with a Compression Gland
Sealing System fitted with a 1/2 Inch Compression
Gland Gasket and Insert. This gasket will seal samples from 1/2
inch diameter down to 3/8 inch diameter.
If you need other sealing
options such as bladed
grass or other semi-round sizes
check our other
options.
A Volume Reducer is not available
for
this instrument.
For extensive research projects you might consider a
Model 1000 or Model 1505D
due to the large range of
operating pressure.
The instrument requires a nitrogen source. You can use it in a
lab or green house with a large cylinder or buy our light weight Portable Tank to allow for
field work.
