MLR-70 is a contact (guided-wave) probe, not non-contact — its FEP-Teflon coating is what carries the chemical-compatibility claim, since the powder-coated aluminum alloy housing never touches the process fluid. Confirm FEP compatibility against the specific acid before quoting rather than assuming the housing rating covers it.
A guided-wave radar probe's housing material and its wetted probe coating are two different compatibility questions — Icon's MLR-70 pairs a non-wetted aluminum enclosure with an FEP-Teflon-coated probe specifically because the probe is what sits in the acid, and Icon markets it by name for liquid chemical storage and chemical sumps rather than generic tank level. Liberty CES specs the wetted coating against the acid in question, not the enclosure rating.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
