INTRODUCTION
The CI-340 Ultra-Light Portable Photosynthesis System is an improved version of the first
lightweight, hand-held photosynthesis system in the world. Featuring a new design concept and
compact solid-state structure, the entire system – display, keypad, computer, data memory, CO
2
/H
2
O
gas analyzer, flow control system and battery – is contained in a single, hand-held case. It has
everything to measure photosynthesis, transpiration, stomatal conductance and internal CO
2.
Because
the chamber is connected directly to the CO
2
/H
2
O differential gas analyzer, there is virtually no time
delay when measuring CO
2
/H
2
O in the chamber. These features make the CI-340 the fastest,
smallest, and most accurate photosynthesis system available for field and laboratory operations.
The unit is designed to perform the following functions: Absolute, Calibrations, Data Transfer, and
Photosynthesis, Transpiration, & Stomatal Conductance. A brief overview for each function is
described in Table 1-1, and covered in detail throughout the manual.
Table 1-1. Description of CI-340 functions:
Absolute
CO
2
concentration measurement (in ppm) for a
single source
Calibrations
Permits the user to calibrate the instrument with
various parameters or settings
Data Transfer Transfers data from the CI-340 to a computer
Photosynthesis, Transpiration, & Stomatal
Conductance
Measurements obtained by using Leaf Chamber
attachments(s) in conjunction with the CI-340
