Liquid Analyzer STC800
The STC800 is a configurable water controller that can adapt to many different probes and configurations, mono or multi-channel, among pH, ORP, dissolved oxygen, conductivity, chlorine, turbidity, total suspended solids (TSS) and temperature.
it includes basically:
“Analog Input – To connect any analog (4 to 20 MA Input) external sensor/Probe Like –
pH, ORP, Chlorine….” Digital Input – To connect any Digital sensor/Probe over RS 485 like –
Dissolved Oxygen, Turbidity, Inductive Conductivity, (pH Digital Sensor) Communication
” 4 to 20 MA Output – Provides 4 to 20 MA signal output to connect external signal device
” Relay – 24VDC Relay helps to configure & control process/dosing with channel of measurement like Chlorine dosing pump can be configure with relay according to the Chlorine measurement from STC800 Multi Channel Transmitter.
