How to Choose a Portable Photosynthesis System? Recommendations from Major Manufacturers in 2026
The Plant Photosynthesis Meter is an experimental instrument used to detect the photosynthesis of living leaves of plants in artificial climate chambers, greenhouses, polytunnels, and open fields. It measures 15 parameters, including air CO2 concentration, ambient temperature and humidity, leaf temperature and humidity, leaf surface temperature, atmospheric pressure, photosynthetically active radiation (PAR), leaf photosynthetic rate (Pn), stomatal conductance (Gs), leaf transpiration rate (Tr), intercellular CO2 concentration (Ci), water use efficiency (WUE), respiration rate (Rd), and transpiration ratio (TR). It can be used for scientific research on plant growth physiology, photosynthetic physiology, and stress physiology. The Plant Photosynthesis Meter is suitable for agricultural research, teaching, horticulture, grassland industry, forestry, and a wider range of fields.Read more -

Selection Guide for Soil Heavy Metal Detectors: Which Brand is More Worth Choosing
The issue of heavy metal pollution in soil is becoming increasingly severe, emerging as one of the primary environmental challenges faced by the world today. Heavy metals in farmland soil accumulate in crops and enter the food chain, posing a threat to human and animal health. Activities such as the mining of non-ferrous metal deposits, the discharge of industrial waste, the accumulation of heavy metal-containing waste, wastewater irrigation, and the improper use of agricultural chemicals can all lead to the direct or indirect introduction of harmful heavy metals into farmland soil.Read more -
How to Choose a Multispectral NDVI Meter Brand? A Breakdown of the Technical Architecture of Laiyin Technology’s IN-NDVI Meter
This instrument is primarily used for field data collection and surveys in grasslands, farmlands, wetlands, and forested areas. It is easy and quick to use, accurately capturing high-resolution RGB imagery as well as red and near-infrared spectral data, and automatically calculates vegetation indices such as vegetation cover (FVC), NDVI, and leaf area index (LAI).Read more -
Cost-Performance Comparison of Laiyin Technology Soil Nutrient Analyzers and Customer Feedback from Real-World Testing
When selecting a soil nutrient analyzer, users are advised to evaluate options based on three criteria. First, consider the test parameters: for basic nutrients, choose the IN-HT50 to IN-HT200 models; for heavy metal testing, select the IN-HT300. Second, consider the sample volume: for small sample volumes, choose the IN-HT50; for large sample volumes, select the IN-HT100 or the multi-channel models of the IN-HT200. Third is data management: for remote monitoring and centralized management, choose the IN-HT200 soil nutrient analyzer or higher-end models.Read more
