HE-480H-DC24V

판넬 장착형 전도도계(4-wire Transmitter , 고전도도용)

HE-480H-DC24V 산업용 전도도 측정기는 고농도 전도도 측정기로 넓은 측정 범위를 제공합니다.
전도도 센서(FES-125F/126F)를 연결하여 시료수의 전도도와 온도를 측정합니다.
모든 종류의 약액 농도 관리부터 수경재배에 사용되는 액비 농도 관리까지 다양한 작업에 적합합니다.

- 측정 범위(전도도) : 0 ~ 50 S/cm, 0 ~ 500 mS/m
- 온도 : 0.00 ~ 100.00 ℃

Base product: HE-480H
  • Capable of measurements in a wide range, up to 50 S / m (500 mS/cm)
    The HE-480H-DC24V 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.
