HE-480H

Industrial conductivity meter (high concentration type) HE-480H

Industrial conductivity meter (high concentration type)

The HE-480H industrial conductivity meter is a high-concentration conductivity meter using a four-electrode method, with a wide measurement range of 0 - 50 S/m. It is suitable for a wide range of tasks, from managing the concentration of all types of medicinal solutions, to managing the concentration of liquid fertilizers used in hydroponic farming.

 

Division: Process Water
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.
  • Capable of measurements in a wide range, up to 50 S / m (500 mS/cm)
    The HE-480H is applicable to many different tasks, from managing the concentration of all types of solutions used as ingredients, to measuring salt concentrations or managing fertilizers.
  • Includes sea salt - NaCl conversion function
    The salt concentration displayed is converted based on conductivity conversion data.
  • Temperature compensation suited to a range of tasks
    You can select the appropriate temperature compensation for the temperature characteristics of the fluid you are measuring.
  • Self-diagnosis function for sensor faults
    The sensor automatically determines whether it has deteriorated, and displays an error message.
  • Uses lead-free solder
    To reduce the burden on the environment, lead-free solder has been used to mount the components on the printed circuit board.
