SANSEL make digital ORP(Oxidation Reduction Potential)/ Redox meter is a precise and rugged instrument Carefully designed for the most accurate measurement of pH in Laboratories and industries. The instruments are completely IC version using “MOFSET” input “OP – AMP” and CMOS ICS. It is a met al cabinet of elegant shape. All the controls that are in regular use have been incorporated in the front panel for operational easy. The instrument is capable of measuring millivolts with auto. Polarity for redox potentials and potentiometric tirations. This instrument Operates from 180V to 230V AC 50Hz.
