UNIPHOS Online UV COD/BOD/TSS Analyser

Enquire Now

The UNIPHOS online UV COD/BOD/TSS analyser is an advanced multi-parameter water quality monitoring system for measurement of chemical oxygen demand (COD), biological oxygen demand (BOD) and total suspended solids (TSS).

The instrument measures the UV transmission spectrum of the water sample at 254 nm for COD and 860 nm for TSS. Based on the absorbance values at these wavelengths, COD and TSS concentrations are calculated. The influence of suspended solids is automatically compensated to correct COD values.

This gives accurate, real time, continuous and reagent-free analysis of COD, BOD and TSS in a water sample.

Application

The analyser is suitable for monitoring a wide range of water samples, including:

  • Industrial wastewater,
  • Municipal wastewater,
  • Surface water,
  • Ground water,
  • Drinking water and process water, etc.

Features

  • No reagents are required for measurement
  • Low operational cost
  • No secondary pollution or waste generation
  • Fast response ideal for real time monitoring
  • Unaff­ected by chloride ion interference
  • Automatic cleaning / purging facility
  • Utilizes high-performance industrial-grade electrodes for long-term stable operation
  • RS-485 signal output ensures strong anti-interference capability and supports long-distance transmission
