1056 Intelligent Four-Wire Analyzer
SKU: 1056
Multi-parameter four-wire liquid analysis transmitter — modular electronics support a wide range of measurement combinations including differential conductivity, dual oxygen, pH/ORP + chlorine, and many more. Drives most industrial, commercial, and municipal liquid-analysis applications from a single transmitter platform. Backlit graphical display with multi-language UI. The mid-tier Rosemount Analytical transmitter — broader sensor support than the 56, less channel count than the 1057.

1057 Triple Channel Transmitter
Triple-channel liquid analysis transmitter — three independent pH/ORP and/or conductivity inputs in one transmitter housing. Reduces installed cost and panel space when a process requires multiple measurements at a single location (boiler-feedwater plants, electrochemistry plants, multi-tank monitoring). Modular sensor-input cards. Same UI family as the 1056. Best when consolidating three sensors that would otherwise need separate single-channel transmitters.
1066 Single Channel Transmitter
Single-channel liquid analysis transmitter — drives one sensor (pH/ORP, contacting or toroidal conductivity, dissolved oxygen, chlorine, ozone, turbidity). Same modular electronics platform as the 1056 / 1057. The single-channel choice for tight panel-space installations where a 1056 dual is over-spec, but a loop-powered 5081 isn't suitable (need full 4-wire operation, broader I/O, larger display).
5081 Explosion-Proof Transmitter
Single-channel loop-powered (4-20 mA HART) liquid analysis transmitter in an explosion-proof housing. Accepts pH/ORP, contacting / toroidal conductivity, and amperometric (DO / chlorine / ozone) sensors. Rugged weatherproof corrosion-resistant enclosure for hazardous-area installations (Class I Div 1, Zone 1) — the Rosemount Analytical choice when other transmitters need separate explosion-proof enclosures and conduit fittings. Loop-powered means no separate power supply or 4-wire conduit run.
56 Dual Channel Transmitter
Dual-channel liquid analysis transmitter — accepts two independent sensor inputs (any combination of pH/ORP, contacting / toroidal conductivity, resistivity, dissolved oxygen, free chlorine, total chlorine, ozone, turbidity). Large color graphical display with intuitive menu structure. Used in water/wastewater plants, chemical process plants, and any installation where two analytical measurements share one transmitter location for cost efficiency.
