WK01+
Condensation sensor with an LED signal and a relay output for condensation detection on chilled surfaces. For control and monitoring applications or connection to cooling valves to stop the flow of chilled water upon condensation detection. The 'ext.' model uses a 2 m remote sensor for a more flexible installation.
