SK80-WAQ-MES - KNX Water Quality Measuring System with pH and ORP Probes
✗
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-MES is a KNX water quality measuring system for pools, spas and technical water, supplied with pH and redox (ORP) combination electrodes. It sends pH, ORP and, with an optional PT1000 probe, water temperature to KNX, and adds two potential-free contact inputs.
The electrodes install in a bypass line and screw in hand-tight. The surface-mount unit has a local LCD and an IP54/65-rated bus coupler, and it runs on KNX bus power alone.
Key Features
- Includes pH electrode HI2114P (0 to 13 pH) and ORP electrode HI3214P (0 to 2000 mV)
- pH 0 to 13 and ORP/redox 0 to 2000 mV electrode inputs, galvanically isolated from KNX
- 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; electrode service life 1 to 3 years
