Sper Scientific Online pH/Conductivity Analyzer monitors one analog pH or ORP sensor and one analog conductivity sensor simultaneously.
It combines two measurement channels in a compact panel-mounted instrument for continuous water quality monitoring in industrial processes, water treatment and wastewater applications.
The pH/ORP channel supports acidity or oxidation-reduction potential measurement, while the conductivity channel provides conductivity, TDS, salinity or resistivity readings. Temperature measurement and compensation support consistent process evaluation when used with compatible probes. Actual measurement range, process temperature limits and overall system performance depend on the sensors selected.
A 3.1-inch backlit LCD displays process readings, while the front-panel buttons provide access to measurement and output settings. Two configurable 4–20 mA outputs and RS485 Modbus RTU communication support integration with PLCs and plant monitoring systems. Three relay outputs provide alarm and supported control functions.
Historical data records and trend curves help review process changes. Recording intervals can be set from 1–999 minutes, and stored data can be exported to a computer over USB. The ABS enclosure has an IP65 protection rating, with standard 100–240 VAC power and an optional 24 VDC configuration.

FAQs
Can the DCA130 measure pH and conductivity at the same time?
Yes. It supports one pH/ORP sensor and one conductivity sensor simultaneously.
Can it measure pH and ORP simultaneously?
The first channel uses a pH or ORP sensor. The second channel is intended for conductivity measurements.
What measurements are available on the conductivity channel?
Conductivity, TDS, salinity and resistivity functions are supported. Available ranges depend on the electrode and configuration.
Can it connect to a PLC?
Yes. The analyzer provides RS485 Modbus RTU and two configurable 4–20 mA outputs.
Can historical readings be exported?
Yes. Stored data can be exported to a computer over USB. Logging pauses while the USB connection is active and resumes after disconnection.
Are sensors included?
Sensor inclusion has not been specified. Select the required pH/ORP and conductivity probes for your installation and confirm the package before ordering.
