加拿大Real Tech REAL UV254 ANALYZER 实时UV254分析仪
参数: UVT, UV254
UV254分析仪
Real Tech的在线UV254/UVT分析仪可快速实时测量水或废水中的有机物输出，如UV254（cm-1）或紫外线透射率/UVT（%）。UV254分析仪利用254nm波长的光，因为大多数有机化合物，特别是芳香族有机物，吸收该波长的光。得益于我们创新的Ortho Beam和Split Sense Pro技术，可以输出准确可靠的测量结果，从而实现有机物监测的最高可信度。
连续有机监测可以为许多应用带来重大价值，包括紫外线消毒性能和效率、混凝剂量优化、DBP形成潜力、水源水监测等。
