B&C Electronics PH 6587 pH/ORP controller – transmitter, wall mounting
The controller can be configured to measure pH or ORP during the installation.
It provides manual and automatic temperature compensation, if an RTD Pt100 or an RTD Pt1000 is connected.
When the RTD is connected, the instruments provides the temperature reading.
FeaturesTechnical DataApplications
The instrument provides:
– measuring display in the range stated by the installed sensor;
– automatic measurement control function
– alarm from the min/max values of the measures, the excessive activation of relays and the presence of the logic inputs;
– programmable dual analog output for recording and acquisition of the measurement values or PID regulation;
– hold / alarm function activated by two external volt free contacts;
– automatic /manual autoclean function.
