Description

INSTRUMENT FOR DIN SLOT – S504-pH/RX/T

Input for pH or ORP electrode + Pt100 sensor

S504-pH/RX/T is a series of single-measurement instruments, suitable for the installation on DIN slot.
The series includes different models, for measuring pH, ORP, conductivity and a version with mA input.
This instrument is the ideal solution for monitoring water in industrial processes, purification and conditioning, in the agri-food and livestock industry.
