With their advanced ultra violet absorption sensing technology, the new family of UV-6 Analyzers from Electro-Chemical Devices (ECD) helps treatment plant engineers and technicians assure the safety of surface and ground water supplies, drinking water disinfection and protect the environment from untreated wastewater effluent.
UV-6分析仪
Relying on their sophisticated UV absorption correlation technology, the ECD UV-6 Analyzers are designed to monitor five separate parameters over a wide range of values. They accurately measure via their spectroscopic sensor at a 254 nm wavelength with correlation algorithms the presence of ammonia, nitrate chemical oxygen demand (COD), biological oxygen (BOD) or total organic carbon (TOC).
这些污染物的分析基于收集样品中紫外线吸收的测量。氨测量可分为两个范围：0至10 ppm或0至1000 ppm。硝酸盐测量可分为三个范围：0至30 mg/l，0至100 mg/l或0至250 mg/l。COD，BOD和TOC的测量分为两个范围：0至200 mg/l或0至20,000 mg/l。
使用长寿命氙气光源和光探测器，通过特定波长的石英流动池测量溶液或气体的吸光度。该吸光度与根据Beer-Lambert Law的样品浓度有关，该法将光的衰减与投影光传播的溶液的特性有关。
UV-6分析仪是从ECD工厂预校准的，这使其易于安装和启动。没有复杂的组装或校准解决方案，不需要特殊的工具或冗长的技术人员安装培训。只需从包装中删除分析仪，将样品，浪费和清洁管线连接，插入式插件并为设备加电。壁挂硬件是标准配置的，并且还提供了可选的台式支架。
This family of easy-to-use analyzers greatly reduces technician maintenance time and consumables expenses. The design of the UV-6 features a built-in spray cleaning system that keeps the light source and sensor cell free from algae growth and sticky particles to ensure accuracy. Best of all there are no costly reagents required, which also must be disposed of properly to prevent environmental contamination.
数据记录是通过RS232通信提供的。包括四个警报继电器，通常打开，在250 VAC时5安培，以及一个4-20 mA输出，分辨率为12位。从多个电源选项中进行选择：110-130 VAC或220-240 VAC /30VA /50-60HZ或12-15 VDC /4A。
