Introdução do produto
Testador de umidade de grãos, medidor de umidade por infravermelho para detecção de teor de água
O medidor de umidade on-line por infravermelho próximo adota o princípio mais avançado internacionalmente de reflexão difusa por infravermelho próximo de três bandas e seis feixes, permitindo medição rápida e contínua do teor de umidade de materiais em esteiras transportadoras, sem contato com o material medido, realizando monitoramento dinâmico em tempo real do teor de umidade do material, com tempo de resposta de apenas5ms, alcançando monitoramento e feedback rápidos em tempo real do teor de umidade do produto, atendendo amplamente aos requisitos rigorosos de gerenciamento de umidade do produto. Devido ao método de medição sem contato, não causa nenhum dano ao material medido, fornecendo assim uma solução precisa e eficiente para o controle de umidade no processo de produção.
An infrared moisture meter is an instrument that uses the principle that water molecules have strong absorption characteristics for infrared light of specific wavelengths to quickly and non-contact measure the moisture content of materials-1-4. It is widely used in industrial production lines as a real-time quality control and process optimization tool-1-5。

💡 Working principle
Its core is based on near-infrared spectroscopy technology: near-infrared light of specific wavelengths (such as1.94μm) irradiates the material, it is absorbed by water molecules, and the reflected light energy is correspondingly weakened-2-4. The instrument calculates the moisture content of the material by analyzing the energy loss of reflected light-1. Common three-wavelength or eight-beam technology can eliminate interference from non-moisture factors such as material color and structure, making measurement more accurate-1-3。
✨ Core advantages
Non-contact measurement: No contact with the material, causing no wear or pollution, suitable for high-speed production lines-1-6-5。
Real-time online detection: It can provide data continuously and quickly (response time can reach millisecond level), facilitating timely process adjustment-2-6-11。
No frequent maintenance needed: Compared with manual oven drying method or electrode method, it does not require frequent calibration, has no wearing parts, and has low usage and maintenance costs-1-4。
High measurement accuracy: Typical measurement accuracy can reachBetween 0.1% and 0.5%-2-5。

🔍 How to choose
Clarify requirements: First, determine whether it is used forOnline production linesOrLaboratory sampling inspection. Online types need a sturdy shell and real-time communication capability, while laboratory benchtop types focus more on high accuracy and sample adaptability-9-10。
Evaluate the material: Different materials (such as dark powders, lump ores, transparent films) have different reflection characteristics for infrared light; it is necessary to confirm whether the equipment can effectively measure your material-1-8。
Consider the environment: If the installation environment has high dust, high humidity, or high temperature, choose a model with good sealing, cooling, and protection functions-5-8。
