Chemitec 50 Series with UV Nitrate sensor
The 50 series instrument is a multi-parameter system allowing 2 or 4 sensor connection including the optical measurement of nitrate using a UV absorption principle.
The Chemitec 50 Series controller and nitrate sensor is distributed in the UK by PPM and is designed for continuous water quality measurement of surface water and final effluent.
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 dissolved organics 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 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.
