UV254 Probe Datasheet

Product catalog summary

Overview
The document provides details on the UV254 measurement technology used for monitoring natural organic materials (NOMs) in water. This technology is beneficial for managing processes such as aeration, chemical dosing, and UV disinfection performance.

Benefits

No consumables, leading to no hidden costs.
Real-time indication of BOD, COD, TOC, and DOC surrogates with measurements every 10 seconds.
Available in titanium, stainless steel, and aluminium options.
Low operating costs due to minimal maintenance, low energy consumption, and long-life LEDs.
Easy installation with a complete system available, Modbus interface for third-party controllers, and automated calibrations saved on the probe.

Applications

Drinking Water and Wastewater: Source water monitoring, coagulation optimisation, DBP formation potential, reverse osmosis, UV disinfection, and distribution system contamination.
Industrial: Food and beverage, dairy, commercial aquaculture, and other industrial markets.
