UV-VIS COD-TSS Probe with Controller
The UNIPHOS online UV-Visible COD/BOD/TSS analyser is an advanced multi-parameter water quality monitoring system for the measurement of chemical oxygen demand (COD), biological oxygen demand (BOD), and total suspended solids (TSS).
The instrument measures the transmission spectrum of the water sample across 200-800 nm wavelength range. From this full spectrum, the absorbance of the interfering molecules like, nitrate, nitrite, colour, suspended solids, etc., are calculated at their respective wavelengths and used for correcting the COD value at 254 nm.
This gives accurate, real time, continuous and reagent-free analysis of COD, BOD, and TSS in a water sample.
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.
- Automatic cleaning of probe with high-pressure compressed air provides higher reliability than the mechanical blade
- No reagents
- Low operating cost
- No secondary pollution
- Fast response, suitable for online real time measurements
- No chloride ion interference
