Our UV254 Probe is manufactured right here in Lisburn, N. Ireland. We provide probes for OEMs in the instrumentation market, as well as, supplying probes and systems to market ourselves.

UV254 Probe


A UV254 probe is a water quality monitoring device that measures UV Transmittance and UV Absorption at wavelength of 254 nanometres (nm) in a water sample, commonly used to quantify the concentration of organic matter and contaminants in water. 

UV254 probes are used for a variety of applications in the field of water quality management and environmental monitoring.

These probes can identify the presence of organic contaminants from industrial discharges, agricultural runoff or wastewater effluents. They are particular effective for measuring inlet water and identifying dosing requirements in a predictive manner.

By measuring UV Absorbance (Abs.) or UV Transadmittance (%) the probe helps detect organic pollutants that might affect water safety and environmental health.

The measurements and data gained from using UV254 probes can assess the quality of drinking water sources, such as rivers, lakes and reservoirs. Elevated UV254 levels can indicate the presence of Natural Organic Matter (NOMs) or contamination. 

UV254 probes are also used to monitor the efficiency of wastewater treatment processes by measuring and verifying final effluent. UV can also be used at drinking Water Treatment Plants (WTPs) at raw water inlet, clarifiers and post-processed water all in real time. A rise in UV254 absorbance can suggest incomplete removal of organic matter, providing insight into the treatment plant's performance.

The sensitivity of UV254 measurements helps users detect contaminants at an early stage, enabling timely intervention to prevent further pollution. Allowing for feed-forward processing and predictive maintenance and highlights the importance of data-driven decisions. UV254 data provides valuable insights for informed decision-making in water treatment processes, environmental management and helps to avoid nasty fines.

The main benefit to using an electronic probe is the data is received in near real-time, combined with our innovative controller you can take full control of how you receive your data and send signals back to your process from any location. Making you the master of your own water.


Measurement Capabilities

UV254 is used to measure real-time surrogate values

Chemical Oxygen Demand

UV254 can measure Chemical Oxygen Demand (COD)

Range:
0 - 2800 mg/L           1mm Probe
0 - 1400 mg/L           2mm Probe
0 - 560 mg/L             5mm Probe
0 - 280 mg/L             10mm Probe 
0 - 140 mg/L              20mm Probe
0 - 56 mg/L               50mm Probe

Lower path length probes are capable of higher ranges of COD and are suited to Wastewater Applications. Higher path length probes are more suited to high purity water situations for detecting traces.
