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.
