Ecowitt Temperature & Humidity Sensor, Blue Plug (type 4S - WS90)

Harsh environment replacement sensor for the newer WS90 WittBoy outdoor sensor array. Designed for use on areas with salt spray and strong winds or extreme environments with a new outer cap and ceramic shield protecting the sensor. Only suitable for the WS90 WittBoy array. Please ensure that your existing WS90 sensor is the new keyed style sensor with blue socket to ensure compatibility by removing the lower sections of the radiation shield. Easily replaced part by removing three screws on the underside of the heat shield and removing the lower plates. Ensure that you do not handle the sensor with bare hands to prevent contamination and only touch the edge of the sensor when installing. Instructions for installation included with sensor.
