The NIWA investigates whether we need to monitor nitrate concentration continuously and looks at progress in practical nitrate monitoring.
This video shows how to use a membrane patch colorimetry field test kit.
The i::scan is a miniature multiparameter spectrophotometer probe for online water quality monitoring.
Michell Instruments has introduced an updated version of its 2-wire Easidew dewpoint transmitter, with a simultaneous analog and digital Modbus RTU output and a rugged 5-pin M12 electrical connection.
The QMA601 process moisture analyser has been updated with an option that makes it suitable for continuous catalyst regeneration (CCR) reforming processes.
The ES70 simplifies specifying complex, multi-optioned sampling systems, not only ensuring the correct options are selected and but also reducing lead times.
The TriOS OPUS spectral UV sensor is able to deliver readings for nitrate (NO3-N), nitrite (NO2-N), organic water ingredients and SAC254.
The Optidew 501 and 401 chilled mirror hygrometers from Michell Instruments offer a faster response to changes in humidity.
Krohne has added two total suspended solids (TSS) sensors and a transmitter to its analytical range.
Emerson's Roxar Downhole Sensor System has been deployed on the Maria field offshore Norway, providing field operator Wintershall with improved well integrity monitoring and offshore safety.
Endress+Hauser has acquired Blue Ocean Nova AG, a manufacturer of inline spectrometers for monitoring quality-relevant process parameters. The acquisition was effective 31 October 2017, and details of the transaction were not disclosed.
The nanoFlu sensor is an online fluorometer for precise and selective measurement of coloured dissolved organic matter, rhodamine, tryptophan and chlorophyll A in green algae or phycocyanin in cyanobacteria.
The enviroFlu is a submersible sensor for the measurement of oil in water. It utilises a UV fluorescence measuring principle rather than the more conventionally used infrared scattering or absorption methods.
The optec Haze Control 4000 photometric converter has been specifically engineered for high-precision haze (turbidity) measurements.
The CL10 sc reagentless chlorine analyser allows for real-time control of disinfection processes by providing continuous readings that indicate when treatment conditions have changed.
