TW-4766B & TW-5266C UV254COD Senser (LR/HR)

Model number：TW-4766B (LR) & TW-5266C (HR)
Power：0.1W (non-wiping)
Dimension：Φ46mm*176mm
Customise：OEM, ODM

Product description:
TW-4766B (LR) & TW-5266C (HR) UV254 COD sensors adopts the principle of ultraviolet absorption, no reagent, no pollution, more economic and environmental protection. This online COD BOD analyser has an all-metal construction and a smaller size.

Overview

TracWater TW-4766B (LR) & TW-5266C (HR) UV254 self-cleaning COD sensors are based on the principle of ultraviolet (UV) absorption. It requires no reagents, ensures pollution-free operation, and offers a more economical and environmentally friendly solution. Drawing on extensive application experience, this chemical oxygen demand sensor incorporates numerous upgrades and innovations compared to its predecessor, featuring an all-metal structure and a more compact design. Equipped with an automatic cleaning device, it automatically compensates for turbidity interference and demonstrates excellent stability even during long-term online water quality monitoring.
