Kacise Rapid COD Chemical Oxygen Demand Meter COD Tester Water Quality Probe Water Quality Monitoring Equipment KCD120
Product Introduction
The COD sensor uses an advanced deep ultraviolet UV LED cold light source, which has a long life and small drift.Adopt international common technology, proven and highly accurate UV absorption method.
No need for sample pretreatment, fast reaction analysis speed, no reagents, no sampling equipment. The sensor has a mechanical self-cleaning function and uses a 550nm compensation light source,It can effectively eliminate the influence of turbidity and chromaticity on the measurement.
Performance characteristics
Dual-wavelength ultraviolate light to compensate for interference and improve accuracy
• Dual optical path: 254nm and 550nm, which can effectively eliminate the influence of turbidity and chromaticity.
• UV absorption method for the determination of organic matter (such as COD TOC, etc.), without reagents,
the sample does not need to be digested, and does not need long-term maintenance
• Fast response speed, the fastest response time is 10 seconds (T90).
• Adopt advanced cold light source UV LED, long life and small drift.
Adopting filter and PD receiver, no consumables, long life and little drift.
• With independent property rights and stable supply chain of key components, the products are extremely cost-effective.
