CI-203 Portable Laser Area Meter

The CI-203 Portable Laser Area Meter uses advanced laser technology to allow researchers a precise and convenient way to measure leaf area (or the areas of leaf-like objects). The high-resolution laser scanner, data logger, and display are all enclosed in a single, hand-held unit weighing only 1 kg. Non-destructive measurements can be performed on leaves of a living plant by simply pulling a leaf through the instrument, enabling collection of data from the same plant throughout its life span.

Precise leaf area measurements may also be performed on tender leaves. A transparent sheath may be used with delicate leaves. All six measurement parameters (area, width, length, perimeter, shape factor, and aspect ratio) comprise a data set and are compiled at the same time. Over 15,000 data points can be stored and transferred to a computer or printer.

Repeatability and Volume Measuring

The CI-203 Laser Area Meter features an optional glass drum conveyor attachment (CI-203CA) to enable large volume, leaf area measurements in a fast, accurate, semi-automated operation. The conveyor attachment completes the ultimate leaf area measurement solution.

Root scanning

The CI-203RL Root Measurement Attachment is an accessory to the CI-203 Portable Laser Area Meter for determining root length and area. The CI-203RL consists of a carrier base, a removable guide that inserts into the CI-203 in place of the handle, and a CI-203RT root tray. To measure root length, simply slide the CI-203 Portable Laser Area Meter over the root tray. The total length of the roots in the tray will be displayed.

Features

• Non-destructive measurements
• Measures area, length, width, and perimeter
• Calculates shape factor and aspect ratio

CI-340 Hand-Held Photosynthesis System

The CI-340 is a lightweight hand-held photosynthesis system. It features a new design concept and a compact solid-state structure. The entire system - display, keypad, computer, data memory, CO₂/H₂O gas analyzer, flow control system, and battery - is contained in a single hand-held case. It has everything you need to measure photosynthesis, transpiration, stomatal conductance, and internal CO₂ concentration, as well as many other factors. Because the chamber is connected directly to the CO₂/H₂O differential gas analyzer, there is virtually no time delay when measuring CO₂/H₂O in the chamber. With CID's carbonate injection CO₂/H₂O generator module, the CI-340 can precisely control CO₂ and H₂O concentrations in the leaf chamber.

The CI-340 can also control temperature and light intensity with the optional temperature and light control modules. Furthermore, a chlorophyll fluorescence module can be attached to the CI-340 to simultaneously measure photosynthesis and chlorophyll fluorescence. These features make the CI-340 a fast, small, and accurate photosynthesis system for research and teaching.

Features

• An entire photosynthesis system in one hand-held case
• Lightweight and truly portable
• Stable analyzer for accurate CO₂ and H₂O measurements
• Open and closed system measurements
• 9 interchangeable chambers for different types of leaves
• Soil respiration chamber and plant canopy attachment available
• Modular attachments include light, temperature control, CO₂/H₂O supply and chlorophyll fluorescence measurement
• The system can automatically control light, temperature, and CO₂/H₂O concentrations in the leaf chamber
• Infrared non-contact leaf temperature measurement
• Measures chlorophyll fluorescence and photosynthesis simultaneously
