LD MULTICHANNEL control instruments are a series of multiple reading digital systems that meet a wide range of applications. They are multiple digital measuring systems for complete control of water treatment and chemicals dosage, ensuring, depending on model, the control on acid (pH) and on a second parameter (by customer request different parameters combination can be set).
