Overview
PN: 610813 Frog Vision UV254 COD sensor uses a deep ultraviolet UV LED cold light source with long lifespan and low drift. Adopting internationally recognized technology and validated high-precision UV absorption methods. No sample pretreatment required, fast reaction analysis speed, no need for any reagents, no need for sampling equipment. The sensor adopts blue, green, and red compensation light sources, which can effectively eliminate the influence of turbidity and chromaticity on measurement.
Product Details
Advantages and Characteristics:
Four optical paths: 254nm and 470530630nm, which can effectively eliminate turbidity and colorDegree impact.
The UV absorption method is used to determine organic compounds (such as COD, TOC, etc.) without the need for reagents,The sample does not require digestion treatment.
Fast response speed, 10 second response time (T90).
The cold light source UV LED used has a long lifespan and low drift. Using filter andPD receiver, no consumables, long lifespan, small drift.
Having independent property rights and a stable supply chain of key components, the products have cost-effectiveness.
