Leaf Area Index (LAI) is the ratio of foliage area to ground area. The LAI-2200 computes LAI from measurements made above the canopy and below the canopy, which are used to determine canopy light interception at 5 angles. These data are fit to a well-established model of radiative transfer inside vegetative canopies to compute leaf area index, mean tilt angle, and canopy gap fraction.
The benefits of the LAI-2200 over other methods such as ceptometry and hemispherical photography are that it:
The portable Jerome® 631-X Hydrogen Sulfide Analyzer displays low-level concentrations in just seconds. It offers an analysis range of 0.003-50 ppm for odor and corrosion control, safety, and leak detection in such industries as wastewater treatment, oil and gas, pulp and paper, and farming. This simple-to-use instrument utilizes an internal rechargeable battery pack or AC power, and is easily carried to suspected sources of hydrogen sulfide for detection and measurement.
The RAE Systems ppbRAE 3000 is the most advanced handheld volatile organic compound (VOC) gas monitor on the market. Its Photoionization Detector's (PID) extended range of 1 ppb to 10,000 ppm makes it an ideal instrument for applications from HazMat/Homeland Security, industrial hygiene, to Indoor Air Quality and military applications.
The ppbRAE 3000 boasts a 3 second response time while including an integrated Correction Factors list that includes 220 compounds—more than any other PID. The large graphic display presents gas type, Correction Factor, and concentration.
Real Time Kinematic (RTK) satellite navigation is a technique used to enhance the precision of position data derived from satellite-based positioning systems (global navigation satellite systems, GNSS) such as GPS, GLONASS, Galileo, and BeiDou. It uses measurements of the phase of the signal's carrier wave, rather than the information content of the signal, and relies on a single reference station or interpolated virtual station to provide real-time corrections, providing up to centimeter-level accuracy.
Root development and function are vitally important for plant adaptation to the environment. The understanding of root biology is critically necessary to facilitate the improvement of crop performance, especially in the face of environmental constraints. The CI-600 is the only instrument available that enables researchers to capture non-destructive, high resolution, digital images to observe the development and function of a plant’s root system.
