UV-VIS200 FULL SPECTRUM PROBE
Tethys full spectrum UV-Vis probe provides a simple way to measure a number of parameters among TSS, NO3, COD, BOD, TOC, UV254 and colour for surface water or industrial/municipal waste water.
UV-VIS200 Full spectrum probe
Tethys full spectrum UV-Vis probe provides a simple way to measure a number of parameters among TSS, NO3, COD, BOD, TOC, UV254 and colour for surface water or industrial/municipal waste water.
The full UV-Vis absorbance spectrum can also be transmitted for spectral analysis or recording.
It is based on a proven light source technology offering a long lifetime (> 10 years).
The probe must be calibrated for each application to gives a COD or BOD or TOC equivalent measurement, at condition that the sample composition stays relatively constant.
An automatic cleaning by compressed air enable a maintenance free operation over long period.
Its associated controller EL200 can control other probes like pH, dissolved oxygen, conductivity and Cl2 to provide a complete monitoring solution.
FULL SPECTRUM UV-VIS MEASUREMENT
USER-FRIENDLY INTERFACE & COMMUNICATION
A USB port enable to download on any USB key the last 24hours recorded measurements as well as a diagnostic file containing the configuration and useful information for remote troubleshooting. The software of the controller can be upgraded by connecting a USB key.
The RS232 port and the RS485 port support the MODBUS protocol to transmit each measuring channel value to a SCADA system. Additional parameters are available like status code, error code, calibration values. The full UV-Vis absorbance spectrum can also be read under the Modbus protocol as a table of 512 float values with starting wavelength and pitch.
