pH and Redox Measurement
Connecting cables and buffer solutionsfor pH, redox and conductivity sensors JUMO dTRANS pH 01Transmitter/controller for pH or redox potential
display of pH or mV/ORP and temperature This instrument measures and controls (depending
on the configuration) the pH value or redox potential of aqueous solutions. switchable from pH to mV/ORP (redox potential) simple, guided calibration procedure Further information: Data Sheet 20.1090 two relays as standard, freely programmable as limit controller or P, PI, PID, PD controller with pulse width or pulse frequency output, or as modulating controller
Simulators for pH/redox potential and conductivity
two electrically isolated analog outputs 0(4) – 20mA or 0(2) – 10V, freely configurable as process value outputfor pH, redox or temperature, or as continuous controller
(option) two logic inputs simulation of the process value outputs, for dry-run commissioning and fault-finding PROFIBUS-DP or RS485/422 serial interface with MODbus/Jbus protocol (option) panel-mounting housing to DIN 43700, IP65 enclosure protection at front wall-mounting housing with IP67 enclosure protection Further information: Data Sheet 20.2530 a simulator can be connected to a transmitter in place of an
industrial electrode or conductivity cell this facilitates the dry-run commissioning of installations for testing connecting cables and investigating faults
JUMO dTRANS Rd 01Transmitter/controller for redox potential
Further information: Data Sheet 20.1090 This instrument measures and controls the redox potential of aqueous solutions. display range +/-2000mV or 0 – 100%
1-point or 2-point calibration (“3-bucket method”) temperature input can be activated as independent measurement channel for further technical description, see dTRANS pH 01 This converts the high-impedance signal from the
ph electrode into a low-impedance signal. stabilizes the signal, independent of the electrical supply can be retrofitted Possible application areas enables the use of longer cables Industrial and municipal water and wastewater engineering,pharmacy and medicine, chemical industry, semiconductor
engineering, plant engineering. Further information: Data Sheet 20.2995 Further information: Data Sheet 20.2535
