UV254 Analyzer – UV254Sense Probe
The UV254Sense UVA/UVT probe is a UV254 analyzer that offers real-time analysis of organic UVA (ultraviolet absorbance) and UVT (ultraviolet transmission) in water.
Thanks to advancements in spectral analysis technology, monitoring organic contaminants in water has become far simpler than traditional lab based methods with online UV254 analyzers such as the UV254 Probe. This probe, which comes standard with UV transmittance and UV absorbance outputs, continuously passes a small flow of water through a gap in the probe. The UV254 Probe shines UV254 light through the water and measures how much light is absorbed (UVA) and how much is transmitted (UVT).
By measuring the light absorbed at a specific wavelength (254nm), UV254 analyzers can determine the concentration of contaminants, including organic compounds that contribute to the formation of disinfection by-products (DBPs). The UV254 analyzer’s ability to detect the absorption of light provides insight into the amount of aromatic (or reactive) organic matter in water. This makes it a highly effective surrogate for monitoring total organic carbon (TOC) during organic removal processes.
Pi’s UV254 analyzers are capable of detecting natural organic matter (NOM), which is present in all water sources. The UV254 absorption tends to favor aromatic compounds, offering valuable benefits when monitoring the potential for DBP formation.
"We at Scottish Water have been using the excellent Pi LabSense 3 and portable UV254 instruments in the field for optimizing our Water Treatment processes for some years now. We find them easy to use and invaluable for detecting and resolving issues in a timely, efficient and effective manner. Two great pieces of kit!”
