CS6603D Digital COD Sensor

Introduction

COD sensor is a UV absorption COD sensor, combined with a lot of application experience, based on the original basis of a number of upgrades, not only the size is smaller, but also the original separate cleaning brush to do one, so that the installation is more convenient, with higher reliability.It does not need reagent, no pollution, more economic and environmental protection.On-line uninterrupted water quality monitoring.Automatic compensation for turbidity interference, with automatic cleaning device, even if long-term monitoring still has excellent stability.

Testing principle

Many organic compounds dissolved in water are absorbent to ultraviolet light. Therefore, the total amount of organic pollutants in the water can be measured by measuring the extent to which these organics absorb ultraviolet light at 254nm.The sensor uses two light sources -- 254nm UV and 550nm UV reference light -- to automatically eliminate suspended matter interference, resulting in more stable and reliable measurements.

Sensor features

Digital sensor, RS-485 output, support Modbus

No reagent, no pollution, more economic and environmental protection

Automatic compensation of turbidity interference, with excellent test performance

With self-cleaning brush, can prevent biological attachment, maintenance cycle more

Measuring Range

pH：-2～16.00pH； ORP：－2000～＋2000mV； Tempreature：-10～150.0℃；
