Manufacture of on-line analysers suitable for measurement of water and waste-water. We manufacture analysers reporting parameters which include TOC (Total Organic Carbon), Ammonia (ammoniacal-nitrogen) and oil film detection. UK representative for WTW, DKK & HF Scientific, 3S, Realtech and Chemitec. The instrumentation covers single and multiple parameter measurement, on-line and field portable meters. Parameters include turbidity, MLSS, ammonium, phosphate, nitrate, pH, D0, conductivity, Oil on water, oil in water, UV absorption and UVT (UV transmission). We also specialise in providing turn key monitoring solutions for water and waste water analysis. These systems include back-panels, secondary enclosures and walk-in analyser kiosks (pre-installation of instrumentation, sample preparation, frost protection, lighting, electrical and sample distribution). Installations are supported by our team of service engineers providing technical support, routine and emergency call-out cover and chemical supply. - Waste water monitoring - Water measurement - Analytical measurement - Water quality instrumentation - TOC analyser - COD analysis - BOD analysis - Ammonia analyser - Nitrate analyser - Phosphate analyser - pH meter - Turbidity meter - DO meter - Conductivity meter - ORP meter - UV254nm measurement - Oil detection - Bes

Chemitec 50 series with S480 UV Organics sensor

The Chemitec 50 series with S480 Organics sensor is designed for waste water monitoring of dissolved organics such as TOC using UV absorption measurement

No Image

The Chemitec 50 Series controller and S480 UV sensor is distributed in the UK by PPM and is designed for continuous water quality measurement of waste water. 

The S480 UV sensor employs the latest UV absorption technology to provide continuous measurement of dissolved organics (TOC/COD/BOD equivalent) without reagent use.

The 50 series controller is available for two or four sensor connection and interfaces with the digital sensor which can be directly mounted into the effluent channel. Alternatively the sensor may be mounted into a flow cell or a sample break tank available from PPM. 

The 50 series controller provides a local display, data recording, USB data transfer and outputs to telemetry. 

The sensor uses a UV light absorption technique and the path length can be changed to accommodate different measurement ranges and increased sensitivity at low concentrations. A version reporting nitrate concentrations is also available.

The robust sensor is fully submersible and is provided with a 10.0m cable as standard. Longer cable and extensions are also available. 

PPM can also provide automatic air cleaning to minimise maintenance and sample acquisition system where in-situ measurement can not be performed.  

Additional sensors to measure nitrate, DO, pH, conductivity, turbidity, MLSS suspended solids and temperature may also be connected to the 50 series controller. 

The sensors are very versatile. They may be immersed directly into a channel or tank. Alternatively the sensors may be mounted into a dedicated flow cell or small tank if there are more than one sample to receive a pressurised feed or pumped sample.
