Tethys Instruments (France) announces the launch of its new generation of online water analyser UV400. Up to 12 parameters can be monitored simultaneously in one instrument. The new design gives an easy access to the flow cell(s) and to any part of the analyser. A USB port enables the download of the measurements and parameters with any USB key. The userfriendly colour touch screen interface gives an easy way to check and calibrate each parameter.
Based on UV spectroscopy for the main parameters (ammonia, COD, hydrocarbons and nitrate) it offers an unparalleled reliability and stability with an extremely low operating cost. Thanks to large bore tubing and optical compensations, the measurements can be done directly on wastewater without filtering (even with activated sludge). A new flow cell design enables very high values of suspended solid (like paper mill wastewater) without risk of clogging. Phosphate is measured by standard colorimetric methods while pH, conductivity and dissolved oxygen are using standard external probes. A low range turbidity cylinder enables measurements down to very low values for drinking water applications. Different interfaces are available: RS485/MODBUS, RS232, GSM modem as well as analogue 420 mA outputs.
