Measuring the moisture content in soil can provide critical information on soil and vegetation health – especially useful in applications like crop irrigation management. Proximal soil analysis using a field spectrometer or spectroradiometer, like Spectral Evolution’s PSR+, provides a window into soil and vegetation conditions. By taking in situ measurements rapidly and without preparing or affecting the sample, spectral information related to the main water features found at 1450-1460nm and 1920-1930nm can provide information on soil water content and be used to derive data on canopy and leaf health.
The PSR+ features:
* Fast, full spectrum 350-2500nm measurement with just one scan
* High resolution and high sensitivity for clean and accurate spectra
* Autoshutter, autoexposure, and auto-dark correction before each new scan for easy, one-touch operation
* Small and lightweight with rechargeable Li-ion batteries for field operation – half the weight of competitive instruments
* Reliable field performance with an all photodiode array platform and no moving optical parts to fail
* Single user operation with optional rugged handheld GETAC microcomputer that provides a sunlight readable screen plus the ability to tag spectra with GPS, digital camera images, and audio notes
* Standalone operation with 1,000 scan storage
The PSR+ is equipped with the exclusive DARWin SP Data Analysis software package so you can take advantage of the following analysis features:
* Automatically saves data as an ASCII file for easy use with 3rd party software
* No pre-processing is necessary
* Collect reference or target data with a single click
* Display reflectance/transmittance data (percentage) or absorbance (logarithmic) versus wavelength
* Access 19 vegetation indices through the DARWin SP software – including water-related indices
* Optional EZ-ID software compares a target sample against a library of known samples
* Custom library module allows you to build your own spectral database as you scan.
