Overview

PN: 610812 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. Using a 550nm compensating light source can effectively eliminate the influence of turbidity and chromaticity on measurement.

Product Details

Advantages and Characteristics:

•Dual optical path: 254nm and 550nm, which can effectively eliminate the effects of turbidity and chromaticity.

• Determination by UV absorption methodOrganic compounds (such as COD, TOC, etc.) do not require reagents,The sample does not require digestion treatment.

• Fast response speed10 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.
