The UV400 & Series 400 are state-of-the-art water monitoring systems specially designed for high reliability and low operating cost.

Using UV spectroscopy for the main parameters (Ammonia, COD, Nitrate, Hydrocarbons), the UV400 and Series 400 are specially suited for water treatment plants to control the process or to monitor the inlet/outlet, as well as for river monitoring or for industrial effluents monitoring.

  • All parameters fit in one enclosure, including ammonia and phosphate
  • New patented flow cell virtually clogging proof even with ultra high level of suspended solid
  • New colour touch screen interface, fast and user-friendly
  • Faster measuring time and improved repeatability by the use of a new high performance DSP (Digital Signal Pros.)
  • Direct access to the flow cell (brush cleanable) and very easy access to any part inside the analyser
  • USB port to download measurements and diagnostic data on a USB memory stick
  • Wifi and Ethernet interfaces available as option
  • RS232 and RS485 included
  • Mono-board concept for easy electronics maintenance

Other main features:

  • Up to 12 parameters
  • No reagent (except NaOH for NH4 and HCl for dissolved H2S)
  • 10-years lamp lifetime
  • Accept unfiltered waste water, even activated sludge
  • Automatic turbidity compensation for COD, nitrate and hydrocarbons
  • Built-in automatic cleaning system
  • Auto-zeroing function
  • Measuring time of 5 seconds for most parameters
  • Can drive a 6-channels multiplexing system
  • Compact size (520 x 390 x 220 mm)
  • Datalogging with RS232 or USB download
  • RS232 port for GSM modem
