Control Station K800 PR - pH + ORP, without pumps

A multi-parameter device is a compact and easily adjustable unit with a four-line display. The electronic measuring system Control 800 is mounted on a flow-regulating manifold board, on which measuring probes and the filter are installed. The base plate measuring 700 x 420 x 10 mm and made of PVC facilitates overall wall mounting. The unit is connected between the filtration pump and the sand filter. After passing through the unit, the measured water returns to the pool system after the sand filter.

 

• Measures and doses pH (pH probe 0.00 ÷ 14.00 pH)
• Measures Redox (ORP) and doses chlorine (ORP probe ± 1,500 mV)
• Temperature probe (0–100 ºC) - available on request
• Two probe inputs for chemical product levels
• RS485 serial port with Modbus protocol communication

The control unit provides the following outputs:
- Four powered relays. Max. 3 A/250 V AC
- Two relays with dry contact
- Four current outputs 4÷20 mA
- Four frequency outputs
