PH/ORP is a precision instrument used for testing and controlling the pH/redox potential of liquids. Adopting electrochemical principles and microcomputer design, it is easy to operate and maintain. Not affected by color, turbidity, colloidal substances, as well as oxidants and reducing agents, it is suitable for measuring various media such as clean water, wastewater, industrial water, chemical reagents, etc. The instrument adopts LCD display to show pH and temperature values; Has multiple alarm control functions.
