Panel-mount Type Conductivity Meter (Four-Wire Transmission, For Low-concentration)
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 connects conductivity sensor (FES-125F/126F) and measures conductivity and temperature in the sample water. 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.
Conductivity: 0 - 50 S/cm, 0 - 500 mS/m
Temperature: 0.00 - 100.00 ℃
