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

Vue d'ensemble

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.

Fonctions

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.
