is designed to connect between up to four pH or ORP measurement functions
(4 inputs) to one output (your meter). If used properly, it will eliminate the need for
four different pH/ORP meters which otherwise would be needed to carry out the same tasks.
Switcher-PH4 allows you to switch 4 pH channels with an easy-to-install,
and easy-to-use unit. You will be able to control all switching functions
from the front mounted switch.
