Sensor Description

Micromac-1000 is a portable and on-line analyzer, available either in mono or sequential multiparametric configuration (MAC-1000 MP), providing the highest level of analytical automation, based on combined high sensitivity colorimetric and fluorimetric analytical wet-chemistry methods. The analyzer can measure any type of water samples; a wide range of applications is available, including high sensitivity methods for nutrients analysis in seawater. Microma-1000 can perform in a full automated way very complex analytical cycles; the results are displayed in concentration units and provided through the analogic or the RS-232 port.
