The ACS-470 handheld plant canopy spectrometer integrates the advanced Crop Circle ACS-470 probe, GeoSCOUT GLS-400, and the latest FieldPAK PS-12 into a portable, easy-to-use detector.The ACS-470 handheld plant canopy spectrometer is an ideal tool for crop surveys and mapping.The data obtained by the system is stored in the SD card.The entire system weighs less than 3.6 kg, making it easy to carry and measure.The FieldPAK PS-12 power supply unit included with the system can be maintained for 5 hours on a single charge. Crop Circle ACS-470 Crop Canopy Sensors can be used to determine conventional plant nutrition status and basic reflectivity information of plant canopy and soil. Unlike previous passive radiation sensors, the Crop Circle ACS-470 is not limited by ambient light – through its unique light source measurement technology, it can be measured both day and night. The ACS-470 handheld spectrometer can easily determine the biomass and distribution of plants or crops on a larger range.The measured data can be used to analyze nutrients, moisture, diseases and other growth conditions of plants or crops. | |||
Multi-channel spectroscopy | |||
The ACS-470 contains three optical measurement channels.Its uniqueness is that users can select measurement bands in the field as needed to achieve customized spectral measurements to meet specific applications.The spectral configuration is achieved by using standard 12.5 mm filters.Unlike other sensors on the market, the ACS-470 is unique in that its spectral reflectivity can be determined without the influence of the measurement height variation.Holland Scientific calls this technology "Pseudo Solar Reflectance" (PSR).This means that the spectral reflectivity represents a percentage, so it is not affected by the change in the distance between the probe and the target.This will open up more than a dozen direct nutritional indicator parameters, which are more advantageous than purely proportion-based parameters. | |||
Easily obtain data | |||
Its included Holland Scientific GeoSCOUT GLS-400 data collector allows easy and fast storage of data into SD cards in text.In addition, by connecting a GPS receiver on GeoSCOUT, data collected by the ACS-470 can be geotagged and can be used in third-party geographic information system (GIS) software. | |||
