Model confirmation
Can I order directly from the values on this page?+
The page supports preliminary selection. Final housing, membrane, cable, dimensions, temperature compensation and controller interface must be confirmed before ordering.
What is needed for an accurate quotation?+
Send the water chemistry, temperature, pressure, mounting, cable, interface, quantity and destination so the complete configuration can be quoted.
