The Sper Scientific 870009A Online Conductivity and Acid/Base Analyzer continuously monitors conductivity, resistivity, salinity, total dissolved solids (TDS), temperature and the concentration of selected chemical solutions.
Paired with a compatible digital conductivity sensor, it supports applications from pure water systems to industrial process water and wastewater treatment. A backlit display provides local readings. Dual analog outputs and RS485 Modbus RTU communication connect the controller to process monitoring systems. Alarm and cleaning functions support routine operation, while historical data recording helps users review measurement trends.
Features
- Multiple measurement modes with compatible digital sensors
- Two 4–20 mA outputs and RS485 Modbus RTU
- High/low alarms and cleaning relay function
- Historical data recording and retention of settings after power loss
- Panel-mount controller with IP65 protection
