pHG-2091D is Dual Channel pH and ORP Analyzer
pHG-2091D is Dual Channel pH and ORP Analyzer,it can connection with pH and ORP sensor at same time, also with 2 ways of 4-20mA or RS485 Modbus communication.
Digital RS485 Modbus or 4-20mA output Residual Chlorine Sensor
Digital RS485 Modbus or 4-20mA output Residual Chlorine Sensor New Residual Chlorine Sensor, it can be directly with RS485 Modbus or 4-20mA output.max pressure is 3bar indicator Free chlorine reduced dependence on pH Application e. g. Swimming pool water, drinking water, sea water Surfactants (tensides) are partially tolerated. Chlorination agents inorganic chlorine compounds: NaOCl (=sodium hypochlorite), Ca(OCl) 2 , chlorine gas, electrolytically generated chlorine Measuring system Membrane covered, amperometric potentiostatic 3-electrode system with electronic inside Electronic Analog version: - voltage output - not galvanically isolated electronics - analog internal data processing - output signal: analog (analog-out/analog) Digital version: - electronic is completely galvanically isolated - digital internal data processing - output signal: analo...
