1057 transmitter has three inputs from sensors and four current outputs that allows to reduce consumption by one circuit and saves panel space.
Input board for pH signal supports pH, ORP measurements and measurements using ion selective electrodes (ISE).
Input board for conductivity signal supports measurement of conductivity and specific resistance, determination of total content of dissolved solids, salinity, as well as allows to plot a graph of percentage concentration for specific applications.
Thanks to modular structure, signal input boards can be replaced in field conditions that simplifies configuration changes. For convenience purposes, real-time measurement data are always shown on the display during adjustment and calibration.
Standard structural features includes insulated inputs, 7 in-built languages, four current outputs 4-20 mA, 4 signaling relays.
Analyzer has in-built preamplifier with SMART technology for electrochemical analog sensors.
