✗ UL Listed
This product has not been certified by an NRTL (UL, ETL, CSA or equivalent). Installation in USA projects may require a Field Evaluation by a recognized laboratory. Consult your local AHJ before specifying.
~ Low Voltage · SELV
This device operates on a Safety Extra Low Voltage circuit — such as the KNX 29V bus or a DALI 16V bus (NEC Class 2). When powered by an NRTL-listed power supply, many AHJs accept non-listed SELV devices. Verify with your local AHJ before specifying.

The SK80-WAQ is a KNX measuring unit for pool and technical water that reads pH and redox (ORP) electrodes and sends the values to the KNX bus. This version is supplied without electrodes, so standard combination pH/ORP probes can be fitted, and an optional PT1000 probe adds water temperature for compensation.

The surface-mount housing has a local LCD, two potential-free contact inputs and an IP54/65-rated bus coupler. It runs on KNX bus power alone.

Key Features

  • pH 0 to 13 and ORP/redox 0 to 2000 mV electrode inputs, galvanically isolated from KNX
  • Works with standard combination pH/ORP electrodes (3/4" x 16UNF / PG 13.5 thread) installed in a bypass line
  • Optional PT1000 input for water temperature 0 to +80 °C (32 to 176 °F) (±0.3 °C (±0.54 °F)) for compensation
  • 2 potential-free contact inputs (S1, S2); local LCD
  • Surface-mount housing; bus coupler IP54/65
  • Bus powered (approx. 10 mA); ETS application S8-WAQ
