Products Information

The Model 1057 analyzer offers three sensor inputs and   four current outputs thus reducing the cost per loop
and saving panel space. The pH signal input board  supports pH, ORP, and Ion-Selective Electrode measurements.
The Conductivity signal input board supports  contacting conductivity, resistivity, Total Dissolved
Solids, salinity and percent concentration curves for  special applications. The modular design 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, 8
embedded local languages, four 4-20mA current  outputs, 4 alarm relays and removable connectors
for power and current outputs.  QUICK START PROGRAMMING: Exclusive Quick
Start screens appear the first time the Model 1057  is powered. The instrument auto-recognizes each
measurement board and prompts the user to configure  each sensor loop in a few quick steps for immediate deployment.

Model 1057 can also derive an inferred pH value called
pHCalc (calculated pH). pHCalc can be derived and
displayed when two contacting conductivity sensors are
used as sensor 1 and sensor 2.
