Leaf area index meter IN-G10

Leaf area index meter

I. Instrument Introduction

The handheld canopy analyser can be widely used in agricultural production and agricultural research. In order to carry out the canopy light energy resource survey, measure the interception of light in the plant canopy, and study the relationship between crop growth and development, yield quality and light energy utilisation, this instrument is used to measure and record the photosynthetically active radiation (PAR) in the 400 nm-700 nm wavelength band, and the unit of the measured values is micromoles on square metre-second (µmol/㎡s). At the same time using PAR readings and GPS positioning information and other parameters can give the leaf area index (LAI) of the plant canopy.

Functional features

The handheld canopy analyser is an all-in-one design, including LCD display, operation buttons, storage SD card, probe sensor, external sensor and so on. The instrument menu is simple to operate, small size, easy to carry. Data storage with SD card and wireless upload (optional) two storage methods, SD card for the market common type card, storage capacity, data management is convenient; wireless upload networking speed, web page can clearly view the measured PAR value, LAI value, zenith angle and GPS positioning information. Power consumption has a reasonable power management programme, the instrument automatically enters the standby state according to the actual situation during the test, when needed, press the wake-up button to wake up the screen to observe the actual data. Measurement mode is divided into automatic and manual two kinds, automatic measurement interval minimum 1 minute, maximum 60 minutes, automatic measurement times up to 999 times; manual measurement according to the actual needs of manual collection can be.
