High cost/performance SWIR (950~1650nm) spectrometer. High dynamic range and high signal to noise ratio. The transmittance, reflectance and with optical fiber measurements are all available. Stable IR light source. Small size, light weight, easy to setup a mobile laboratory. High precision: NIRez uses professional spectral analysis algorithms for data processing, which can realize quantitative and qualitative analysis of samples, and can obtain high-precision analysis results. Non-destructive detection: NIRez uses infrared spectroscopy for detection, which does not require destructive chemical analysis of the sample, thus enabling non-destructive detection. Easy to operate: NIRez is easy to operate. The user only needs to put the sample on the sample stage, start the instrument to perform spectral analysis, and obtain the analysis results quickly. High cost performance: Compared with spectrometers in the same band, the price is less than half of them. The application of NIRez in smart agriculture has the characteristics of precision agriculture, time and cost savings, and monitoring and prediction. NIRez is an infrared spectrometer that can be applied in various fields, including agriculture. Smart agriculture is an agricultural model that utilizes emerging technologies to improve agricultural production efficiency and yield. The application of NIRez in smart agriculture mainly lies in detecting the infrared spectra of crops, soil, and water quality, thus achieving the following characteristics: Precision agriculture: NIRez can perform non-destructive testing and quickly obtain the spectral characteristics of samples, thereby measuring and analyzing crops and soil more accurately. This can help gain a better understanding of the growth status of crops, soil nutrient content, and other information to achieve precision agriculture. Time and cost savings: Using NIRez can save time and cost of sample analysis. It can achieve non-destructive testing, eliminating the need for destructive chemical analysis of samples. It can also obtain the spectral characteristics of samples in a short period, saving time and cost of sample analysis. Monitoring and prediction: NIRez can detect the spectral characteristics of soil and water quality, understand soil and water pollution, and achieve monitoring and prediction of crops. This can help farmers discover potential problems in advance, take corresponding measures, and improve crop yield and quality.
