and Wiring with detachable plug-in connectors
Applications
CON 200: Use for plating
tank, rinse water, boiler and cooling tower, feed water and blowdown control,
font solution make-up and control for printing, photographic developing,
chemical production process, ion exchange systems, R.O. systems, industrial
process water, wastewater, dilute acids, salts and bases.
TDS200:
Ideal for drinking water, monitoring and control, hydroponics and
aquaponic solution balance and control, pools and spa hardness and salinity
control.
