The Model 1056 dual-input analyzer offers single or dual sensor input analysis with an unrestricted choice of dual measurements thus reducing the cost per loop and saving panel space. This multi-parameter instrument offers a wide range of measurement choices, including differential conductivity, dual oxygen and many other combinations supporting most industrial, commercial, and municipal applications. The modular design of the instrument allows signal input boards to be field replaced making configuration changes easy. Conveniently, live process values are always displayed during programming and calibration routines. Standard features include isolated inputs, 6 embedded local languages, two 4-20mA current outputs, removable connectors for power and current outputs, four solid plugs for closure of openings, and panel mount hardware.
