Profile: C L R Srl specializes in designing and manufacturing sensors & instruments for electrochemical analysis. Our pH, ORP, ISE products include simple and combined electrodes for the measure of pH & ORP, many Ion Selective Electrodes (ISE) and a wide range of reference electrodes. Our electrodes are suitable for laboratory use and for industrial applications. We manufactures polarographic sensors for dissolved oxygen, 2 electrodes, membrane type. We have developed a cell for the selective measure of chlorine & oxidising substances at low and high concentrations, the cell measures chlorine, chlorine dioxide, chlorites, ozone, bromine, permanganate, peracetic acid & hydrogen peroxide at low concentrations (0¸ 2000 ppb & 0¸ 10.0 ppm) & high concentrations (0¸ 2000 ppm).
