The PMR-5 is a steady-state,
continuous flow porometer
designed to be used with our popular
EGM-4 CO2
analyzer.
The EGM-4 supplies the power, measures
the outputs from the porometer
sensors, processes the results and
then displays and records the data.
The PMR-5 is a hand-held unit using
and "open system" measurement of leaf
transpiration. There is an integral
mass-flow controlled air supply and
manual control of humidity up to
ambient.

The Soil Respiration System consists
of the SRC-1 Soil Respiration Chamber
and either the EGM Environmental Gas Monitor or
CIRAS Differential CO2/H2O
Infrared Gas Analyzers.The method of
measuring soil respiration is that
described by Dr. K.J. Parkinson in
1981, where a chamber of known volume
is placed on the soil and the rate of
increase in CO2
within the chamber is monitored. In
the original method, air samples were
withdrawn at one minute intervals and
separately analysed. With this system,
the air is continuously sampled in a
closed circuit through the EGM or
CIRAS, and the soil respiration rate
is calculated, displayed and recorded
by the analyser. The air within the
chamber is carefully mixed to ensure
representative sampling without
generating pressure differences which
would affect the evolution of CO2
from the soil surface.

A transparent cuvette to allow for
closed system measurement of
photosynthesis and respiration in low
plant canopies or soil. The cuvette
can be used with either CIRAS or EGM
range of analyzers. |
