pH and Millivolt Meters for Accurate Ion Measurement - pH-410 & pH-420

pH-meters-millivoltmeters mod. pH-410 and pH 420 (hereinafter referred to as pH-meters) are designed to measure the activity of hydrogen ions (pH), redox potential (Eh) and temperature of aqueous solutions. Description of measuring instrument The pH-meter is an electronic device based on a microprocessor that converts the electrical signal of the measuring electrode systems into a digital code and a set of electrodes. ? To exclude the influence of the temperature of the measured solutions, the mode of automatic thermal compensation is provided.
