Multi-elements analyser for on-line and continuous measurement of dissolved heavy metals.

APPLICATIONS
Industrial and urban water analysis. Self supervision water treatment plants : Drinking waters, Surface waters, Process control.

OPERATION PRINCIPLE
The Heavy Metals Analyser uses the technology of the polarography, which gives it selectivity, sensibility and precision completely adjusted to heavy metals analysis present in liquids at trace level, and up to concentrations of several mg/l. The automatic calibration based on standard addition principle is carried out in the measurement environment for each sample. It allows independence of possible drifts linked to the composition of the sampling and increases measurements precision. It also takes into account failures detection. Wide measurement ranges are possible due to the self adjustment of the dilution system. The polarographic sensor used is a very powerful sensor from new generation, i.e. simple, reliable and using few reagents.
